Preview File Before Download

[likestuff]

Is it possible to display a image thumb of the download to preview before downloading?

I have "Display Preview Button" set to Yes, but I don't see a button on the frontend to preview the file.

Thanks!

Hi,
see this guide. It describes to preview a pdf but it should also work with jpg
