In Umbraco 8 the following code worked:
#using Umbraco.Core.PropertyEditors.ValueConverters;
#{
Layout = "Main.cshtml";
var imgCropper = item.Value<ImageCropperValue>("homeImage");
var thumbUrl = imgCropper.Src + img.Cropper.GetCropUrl("Thumb");
}
In Umbraco 9 it gives me
The type or namespace name 'PropertyEditors' does not exist in the
namespace 'Umbraco.Core'
This line from up to date documentation does not work too:
<img src="#Url.GetCropUrl(Model.HomeImage, "thumb", true)" />
Giving me
'IUrlHelper' does not contain a definition for 'GetCropUrl' and the
best extension method overload
'FriendlyImageCropperTemplateExtensions.GetCropUrl(IPublishedContent,
ImageCropperValue, string, UrlMode)' requires a receiver of type
'IPublishedContent'
What is the correct way to display a thumbnail from image cropper in Umbraco 9 if image cropper fields is named 'homeImage' and it has a thumbnail named 'thumb'?
Found the solution 2 minutes after posting the question (d'oh). The command must be as follows:
<img src="#Url.GetCropUrl(Model.HomeImage, "thumb")" />
Please note there is no last parameter (true), that's what caused the problem.

I have tried for more than two hours and I can not find an answer to this problem. I have this part of the code in a view strongly typed in MVC:
<td>
#foreach (var TitleBook in Directory.GetFiles(Server.MapPath("~/App_Data/Images"), "*.jpg"))
{
var fileName = Path.GetFileName(TitleBook);
if (Convert.ToInt32(fileName.Substring(0,3)) == item.IdBook)
{
<img src="#TitleBook" alt="Alternate Text" height="100" width="100">
}
}
</td>
The name of the image file is created so the three first characters in the filename are numbers.
When I run the code, I get the alternate message for the image in the hmtl view. However, the path to this image is well read and I know it because I can obtain it by doing inspect in the browser and calling only the src part of in another window which shows the image as expected (sorry for my English). The css is handled by the version of boostrap installed in VS2017.
Could someone point to my error here?
Your titleBook is a full physical path. But <img> wants an URL.
Untested:
<img src="~/App_Data/Images/#fileName" alt="Alternate Text" height="100" width="100">
BTW: with Directory.GetFiles(..., $"{item.IdBook:D3}*.jpg")) you wouldn't need the foreach loop.
So, I'm currently new to Umbraco and I'm following some tutorial videos on umbraco.tv. I have created my template and is currently using it to setup the Home Page for my website. I have all the front end working and its displaying properly.
My problem is on the images. I'm using a lot of images for my website and I'm trying to link it to content so the images can be easily changed(not sure if I'm making sense).
Navigation bar image
If you click the link above, that's how my current navigation bar look like. I want to be able to change the LOGO using Umbraco's media picker. However, everytime I do so, it either gives me the alt name or a runtime error.
This is the code for the image on the template.
<img src="#Umbraco.Field("navigationLogo")" height="100" width="50" alt="Logo">
I'd appreciate it if you can help me. I'm not sure if I've explained it properly so feel free to ask in detail. Thanks!
Edit -----
I am only coding on browser since it doesn't allow me to login to pull the codes locally (only on trial version since I'm just testing out if its a good CMS).
Not sure if I'm doing it correctly so I apologize. I wrote my code like this
#{
var navigationLogo = #Umbraco.AssignedContent.Site().GetPropertyValue("navigationLogo");
var navigationLogoMediaItem = #Umbraco.TypedMedia(navigationLogo);
<img src="#navigationLogoMediaItem.Url" height="100" width="50" alt="Logo" />
}
It's giving me the following error so far.
Compiler Error Message: CS1061: 'Umbraco.Web.UmbracoHelper' does not contain a definition for 'AssignedContent' and no extension method 'AssignedContent' accepting a first argument of type 'Umbraco.Web.UmbracoHelper' could be found (are you missing a using directive or an assembly reference?
#inherits Umbraco.Web.Mvc.UmbracoTemplatePage
#{
Layout = "WebBase.cshtml";
string navigationLogoMediaItem = "";
if (Model.Content.HasValue("navigationLogo"))
{
navigationLogoMediaItem = Model.Content.GetPropertyValue<IPublishedContent>("navigationLogo").Url;
}
}
<img src="#navigationLogoMediaItem" height="100" width="50" alt="Logo" />
you can try this
I'm going to make a few assumptions so please bear with me here.
Assumption 1) On your home node (assuming a document type of 'home") you have a property on it called "navigationLogo".
Assumption 2) This is a media picker data type
Assumption 3) You are using Umbraco 7.6 or newer.
Assumption 4) You aren't using Models Builder
So, assumptions in place there are a few steps you need to go through.
1) Get the navigation logo where ever you are in the site.
var navigationLogo = #Umbraco.AssignedContent.Site().GetPropertyValue("navigationLogo");
2) next, you'll need to get the media item as I belive you will only have a UDI at this stage.
var navigationLogoMediaItem = #Umbraco.TypedMedia(navigationLogo);
3) You'll want to put a null check in at this point but to get the url of the logo you simple need to do this:
<img src="#navigationLogoMediaItem.Url" height="100" width="50" alt="Logo" />
That should get you what you are after. :-)
You can simply try out this code.
memberImage is your document type field name
#{
var image = Umbraco.TypedMedia(#Umbraco.Field("memberImage").ToString());
<img src="#image.Url" style="max-width:250px">
}
I'm building a image slider using Archtype in Umbraco.
I was using umbraco 7.5.9 and Umbraco.MediaPicker when I started this but in the mean time I started a new project with the newest version Umbraco (7.6.2) which uses Umbraco.MediaPicker2
It was no problem rendering images with the old MediaPicker but with the MediaPicker2 it seems impossible.
Here is my setup.
The Archtype:
Here is the partial view that rendered the old MediaPicker
<div class="fullWidthSlider">
#foreach (var image in #CurrentPage.SliderImages)
{
<div>Id: #image.GetValue("image")</div>#*Line added for debug*#
var media = #Umbraco.Media(image.GetValue("image"));
<img src="#media.Url" />
}
</div>
This used to work for the old Media picker and the #image.GetValue returned int id. But with the new MediaPicker2 it returns Umbraco.Core.Udi[]
If I foreach through the properties of the archtype with the code below I get this result (see below code)
#foreach (var fieldset in Model.Content.GetPropertyValue<ArchetypeModel>("sliderImages"))
{
foreach(var prop in fieldset.Properties){
<p>#prop.Alias - #prop.Value</p>
}
}
href -
altText - alt test
image - umb://media/c33bfe07a82b4df18a79db154139cb91
href -
altText - Fjall
image - umb://media/40d5778d34bb4035b5146c901de75212
Can anyone tell me how I can render image from this data.
Thanks
I just went on a roller-coaster figuring this out!
You can get an IPublishedContent from your image string using this code:
// Your string which is retrieved from Archetype.
var imageString = "umb://media/c33bfe07a82b4df18a79db154139cb91";
// Get the guid from this string.
var imageGuidUdi = GuidUdi.Parse(imageString);
// Get the ID of the node!
var imageNodeId = ApplicationContext.Current.Services.EntityService.GetIdForKey(guidUdi.Guid, (UmbracoObjectTypes)Enum.Parse(typeof(UmbracoObjectTypes), guidUdi.EntityType, true));
// Finally, get the node.
var imageNode = Umbraco.TypedMedia(imageNodeId.Result);
Check out this thread on Our Umbraco which covers this issue.
I used this comment to figure out how to get the ID from the image's guid.
It looks like Umbraco HQ is pushing for people to use the new ModelsBuilder with typed models. I'm not sure if Archetype is supported by the ModelsBuilder which is why there's so much trouble.
I personally use Nested Content on all of my projects as it performs the same functionality but (IMO) is better supported by Umbraco because it uses Document Types to store repeatable content schema. Because of this, it can then easily be mapped to IPublishedContent and therefore is supported by the ModelsBuilder!
Hello stackoverflow people
hope you can help me with maybe a simple question, but couldn't find a solution elsewhere and I have just been working with umbraco for a week now and have never used the mvc part before so all is new for me.
So the big problem is how I make a macro to show these images I choose from the multiple media picker the macro should just end with showing.
<img src="img1.gif" height="50" width="50">
<img src="img2.gif" height="50" width="50">
And so on depending on how many images there is. (the size is just an exempel)
I tryed somthing like this
#var selectedMedia3 = #Library.MediaById(Model.mainImage);
<img src="#selectedMedia3.umbracoFile" width="#selectedMedia3.umbracoWidth" height="#selectedMedia3.umbracoHeight" alt="#selectedMedia3.Name"/>
}
But I dont know how to parse the id of the image to the macro.
and when I choose more than one file I need a loop, but dont know how to loop the multiple media picker data, so im a little lost by now.
Are you able to let us know what version of Umbraco you are using. Umbraco has gone through a number of fundemental changes in various version over recent years. The below code should guide you in the right direction for Umbraco 7 Multiple Image picker with the propertyAlias partnersLogos.
#if (Model.Content.HasValue("partnersLogos"))
{
var partnersImagesList = Model.Content.GetPropertyValue<string>("partnersLogos").Split(new string[] { "," }, StringSplitOptions.RemoveEmptyEntries).Select(int.Parse);
var partnersImagesCollection = Umbraco.TypedMedia(partnersImagesList).Where(x => x != null);
foreach (var partnerImage in partnersImagesCollection)
{
<img src="#partnerImage.Url" alt="partners logo" />
}
}
If anyone makes the same mistake as me and doesn't realise that there is a difference between the now obsolete media picker and the new media picker "Umbraco.MediaPicker2" (true from at least 7.6.1) then please read the documentation on Umbraco's web site.
https://our.umbraco.org/documentation/Getting-Started/Backoffice/Property-Editors/Built-in-Property-Editors/Media-Picker2
#{
var typedMultiMediaPicker = Model.Content.GetPropertyValue<IEnumerable<IPublishedContent>>("sliders");
foreach (var item in typedMultiMediaPicker)
{
<img src="#item.Url" style="width:200px"/>
}
}
I'm not really sure if you question is how to setup MVC within umbraco or getting values from an image picker.

How can I create a dynamic url to display an image?
I am creating a web page that lists search results of products and their associated images.
I tried using Url.Content, but it does not format the url correctly.
Code I created:
<img src="../../Images/<%: product.PicFileName %>" alt="photo" />
Html that was output:
<img src=".. ..="" Images="" nopic.jpg="" alt="photo" ="">
I also tried creating a helper method but it created the exact same output:
public static string GetPicUrl(string picFileName)
{
string picUrl = "../../" + picFileName;
return picUrl;
}
Just tried this:
<img src="<%: Url.Content("/Images/" + filename) %>" alt="foo" />
where filename = "foo.jpg" and it gives me
<img src="/Images/foo.jpg" alt="foo"/> which links to http://hostname/Images/foo.jpg
Please let us know what format you want the Url in if this isn't what you had in mind and I will try to help you some more.
