Inspired by the idea from Chris Campbell , who was inpired by the TargetAlert extension for Mozilla firefox, this plugin will place an icon unobtrusively next to your file link, indicating what file type lies behind the link.
Just place the
<txp:mrz_file_preview /> (will show a single file wrapped in a div tag) or
<txp:mrz_file_preview_list /> (presents a list of files in ol or ul tags) tag wherever you want in your article or article form. The file list can be filtered by ID, Category, Filename or No. of downloads. You can see an example of the output here
