Hi,
which template file(s) are available to restyle the typical image/file upload table into a grid of thumbnails? Or is there a module for this?
The second picture is just a quick copy/paste photoshop version of how it should look like:

Knowing the specific div elements etc. would be helpful to put the file labels/info and the renamed "remove" button ("x") as overlays on the thumbnails, if that's possible, as a specific theme override. I'd ideally render the "Headline" (title) field as a placeholder in the text box.
The dev tools are showing draggable odd or just tr.even, tr.odd, or sticky-enabled tabledrag-processed tabledrag-handles-shown sticky-processed sticky-table, but i have no idea where the template part is coming from. tr.even, tr. odd should stay untouched of course since it is necessary for any other table on the site.
