I want to be able to provide my website users with the ability to upload a profile picture. What are my options? What is the best way to do this? I would need to be able to limit the image size, crop / resize the image so that I can display thumbnails of the image. The website is written using Ruby on Rails
In alternate plugin to manage your upload file is carrierwave
The PaperClip plugin is pretty much the new hotness (standard):
http://github.com/thoughtbot/paperclip
It supports different image processors but we use ImageScience. RMagick leaks memory
I agree with the others recommendation of Paperclip for handling any kind of upload.
However for profile pictures in particular, if you are storing your user's email addresses you might like to consider using Gravatar, as StackOverflow does, to effectively "outsource" this functionality and let your users maintain consistent avatars among all the sites they use.

I need a user to upload an original file and process that into a thumbnail (paperclip's got this - check).
Then I would like to be able to retrieve different styles for that attachment, but I do not need to store those different styles on disk anywhere. I would prefer they are generated during the request.
The reason for that is that these styles are single-use. So, paperclip becomes a glorified one-time-use image resiszer. I'd prefer not to incur the S3 cost if I don't have to.
Wondering if there'a way to do this out of the box. Or, maybe carrierwave supports something like this?
Thanks!
I'm pretty sure that the Refile library supports it. Refile is basically a modern version of the Carrierwave, written by the same author.

I would honestly appreciate feedback, or an on edit, on what I should change about this post instead of all the down votes. I'm new to web development, and I had an honest question. If this isn't the place to ask it, please point me in the right direction.
I have a Ruby on Rails application where part of the core purpose involves displaying images that I pull from the Facebook Graph API. And I want to be able to display the images in a uniform size.
What I'm hoping I can do: I'm trying to just store the id of the image from Facebook to my database and resize the image after I pull it from Facebook's servers. I was thinking that this would save on storage costs. I've been looking at the RMagick gem that binds Ruby to the ImageMagick library, specifically their resize method.
Another option I've considered: I'm thinking about adding a cropping feature. To do this though, I think I would need to set up a storage service, like Amazon's S3. Then I would pull from the image storage service where the cropped images are stored instead of pulling from Facebook and resizing client-side.
Are there any options I might not be considering? And how accurate are my examples to approaches that could be taken.
If you have a huge number of images to show, then go with "resize - store - show". If less then go with an on-the-fly process.
Here are a few well-known gems that help you process images, but choose according to your requirement:
CarrierWave
Paperclip
Dragonfly
refile (new gem)
See "Compare CarrierWave ,Paperclip and Dragonfly in rails" and "Refile: Fixing Ruby File Uploads".
I am new to Rails and have been diving into many tutorials and online material. I am now beginning to plan/develop my own app. From all the reading I have done I am yet to come across an industry standard way of handling user profile pictures. I have bullet point what I intend to do (below) and would like some suggestions whether this is a good approach and on the right track or whether there is a much better/secure/standard way:
add a 'ProfilePhotoPath' column to my User Model/Table of type String, which will hold the location path/name of the photo
on sign-up form implement an image upload functionality to upload profile pic and store at specified location (reference in step 1 above)
note: I have come across the 'paperclip gem' and 'imagemagick', is this a better easier approach to what I want to achieve?
There are two better ways to upload profile image using Carrierwave or Paperclip.
If you want to use Carrierwave then refer this tutorial Image Upload using Carrierwave
And if you want to go for Paperclip, then refer this links Upload image using Paperclip video tutorial
Another link with steps is Upload profile image using Paperclip
Most people use Paperclip or a more robust solution would be Carrierwave.
Both are really good. I would tell you to learn Paperclip first.
It's fairly easy if you're just starting out.

I'm using s3_direct_upload to directly upload images from my rails app to an S3 bucket. This is all working fine, however now I'd like to resize the images once uploaded, creating a thumbnail and various other versions.
The approach I can think of taking is using the URL that's posted back from s3_direct_upload to then create a new object in my app in the background, process using RMagick and then reupload these versions to S3. However, this approach feels like the initial upload becomes a little redundant.
Any advice on this or a better approach would be greatly appreciated.
Updated Answer
You mentioned in a comment to my original answer that you'd tried CarrierWave. But...have you tried out CarrierWaveDirect? I haven't used it myself, but it appears to perform the same S3 direct-uploading, with the familiar API of CarrierWave.
Original Deprecated Answer
You'll probably want to look into either Paperclip or Dragonfly. They each support uploading images to S3 (or other cloud storage provider), and also provide features for manipulating the images. The two solutions handle manipulations in different ways--Paperclip performs thumbnailing at upload-time, whereas Dragonfly performs thumbnailing on-the-fly--but either should meet your needs.
I am building an app where user can upload pictures. For now only one picture at a time will do. I have searched around the Web and here at Stack Overflow, but don't really seem to find what I am looking for or at least I don't know what I am looking for if it exists here at the site.
I have tried implementing paperclip and allow users to upload pictures through that and not deleting the old picture when uploading a new one. But I don't really know where to go from here to display all the pictures that a user has uploaded. How do I do this the best way? Should I continue using paperclip or is there an even more suitable gem for my needs?
I prefer carrierwave, over Paperclip, because it has more options and easy to setup. However without knowing what is your ultimate goal for your photo app, it's a little hard to tell what to do next.
If you have a roadmap or feature list, that would be helpful for us to help you with your next move.
But, if it is a simple photo app, might as well try to build it on top of an existing CMS like Refinery; you could easily build a plugin to upload images with Refinery.
