Get Image Path from Images Directory in Supporting Files - ios

Question

I have a bunch of images stored in an images directory within my Supported Files directory in Xcode. I want to be able to show one of those images. What is the best way to obtain a path to that image? Do I have to copy them to the Documents directory first? If so, how can I do that?
EDIT: I've tried the following to copy the image from Supporting Files to the Documents folder in the app. It successfully copies, but I can't get the image to show:
-(void)findImage:(NSString *)imageName
{
// First, test for existence.
BOOL success;
NSFileManager *fileManager = [NSFileManager defaultManager];
NSError *error;
NSArray *paths = NSSearchPathForDirectoriesInDomains(NSDocumentDirectory, NSUserDomainMask, YES);
NSString *documentsDirectory = [paths objectAtIndex:0];
NSString *appImagePath = [documentsDirectory stringByAppendingPathComponent:[NSString stringWithFormat:#"%#.jpg",imageName]];
success = [fileManager fileExistsAtPath:appImagePath];
if (success)
{
return;
}
// The writable database does not exist, so copy the default to the appropriate location.
NSString *defaultImagePath = [[[NSBundle mainBundle] resourcePath] stringByAppendingPathComponent:[NSString stringWithFormat:#"%#.jpg",imageName]];
success = [fileManager copyItemAtPath:defaultImagePath toPath:appImagePath error:&error];
if (!success)
{
NSAssert1(0, #"Failed to create writable database file with message '%#'.", [error localizedDescription]);
}
self.imageDisplay.image = [UIImage imageNamed:appImagePath];
return;
}

This should do the trick:
[UIImage imageNamed:#"someImageName"];
EDIT:
Some additional information:
-imageNamed: will look through the entire main bundle of the application for an imagefile (preferrably an png) with the filename of "someImageName". You need not worry about its location or its extension, since it will be searched for in the mainbundle. Files that you import through the import-file-dialogue in xcode will be added to he main bundle.
This means:
If i have imported a file called myImage.png, calling [UIImage imageNamed:#"myImage"];from anywhere in my code will get me a UIImage-Object containing that image. Its amazingly simple, and maybe that startled you a bit ;)
