Overrides don't seem to be working for me. I made the change suggested here and nothing happened differently. I tried adding a simple horizontal rule and that didn't work. I verified that I was editing the right template file. I removed the customization then edited the file again and simply changed the save.png to add.png and it did not work. The changes are saved in the view edit but nothing changes on the file upload.
I can setup a user for you to access the site if you like. This seems so simple yet I can't make it work.
It's because you're not doing the modification for the correct template I suppose.
The product/selectfile.php file is a back end view file, so you should edit it for your back end template, and not for the front end template.
