photo preview of files

Is there a way to add a photo preview of a file?

My members have asked this question as well.  My plan was to make changes so they could add an image to the description field.  If anyone wants to help with this it would be nice; I am busy and these little bits get pushed aside.

The only reason is because the "?" or the Document image on every file just makes it less appealing. If anyone has found a way to do this please share

To change the icon to a preview of the file is more involved than just allowing an image to be included in the description.  The description field of files does not allow html; so one can not insert an image tag in the description field; the tag is stripped out by htmlpurifier.  The easiest solution is to allow that field to include an image tag.
