Thumbnail for Download element

Hey guys,

I've got four open issues in our issue tracker, all requesting roughly the same thing: Thumbnails for download elements. For some of our sites, we offer an image people can download and color in (*sugar* CRAYONS CRAYONS CRAYONS CRAYONS!). This is set as a download element, and offered as such.

However, this isn't very neat for the user - they want to be able to see what they're downloading. A thumbnail, if you will. Of course, this can be implemented by adding an image in front of the download element and style that, but that's not as friendly as it can be.

So my question: Can you cast a MediaItemDownloadVersion object to a MediaItemImageVersion in JSP, and if so, how? And, more importantly, is this recommended, or should I find a different solution?

Solved

Why not simply make a design that shows the thumbnail, based on the assumption that the download file contains an image? I'm thinking along the lines of:

<wm:image var="photo" url="http://www.gx.nl/images/picture.jpg"
alternat iveText="a picture" ></wm>
${photo.htmlTag}

(Copy/pasted straight from the tag library quick reference)

Greetings,

Patrick
