Uri_ImageViewHelper // Link to a resized image
I think this is not possible for the moment. Either you display a (resized) image or you link to the original image (fullsize). So I think it would be nice to have a viewhelper for linking to an image, providing width/height settings.
Here's the implementation of a ViewHelper that works like ImageViewHelper, but just renders the URI, not the whole <img>-Tag. It is based on the original ImageViewHelper and simply returns the $imageResource. Useful for the creation of XML-files where the URI of a resized image is needed.
