How to add thumbnails to uploads?

Just wondering how people do it?

Now seriously. For new uploads, there's a box to tick at the bottom of the upload form

For resources you have already uploaded, if you are on the overview tab of the respective resource, there's the option Edit Resource Icon on the left, under the red Join the discussion button
