Thumbnails, Can No More 'upload Them Manually'

Thumbnails, can no more 'upload them manually' - how is this done int eh latest CS Cart (need clean images for google)

I believe this will need custom modification to bring it back. Contact a developer to do this (

Please take a look

There is no way to upload a custom thumbnail on the product editing page now; thumbnails will be generated automatically from the images that you drag and drop. We don’t take decisions to remove functionality lightly, but having custom thumbnails along with drag-and-drop of images would overcomplicate the interface. However, the ability to upload custom thumbnails via product import still remains.
