Images and gallery watermarks

Is it possible and how to change the watermark in all pictures?

Hello

a simple trick is to also change the width or height of the thumbnails (small, medium, large)
by 2 or more pixels
- when the image field will be view in item or in category view, the thumbnails will be re-created

Currently there is an all-thumbnail delete task button

The problem is that only some of the thumbnails change.
What happens if I delete all thumbnails manually?

Hello

yes you can do the thumbnails
no problem with it

just check that you a thumbnail folder that does not contains also other files or other images

Where is this button?

Something I think I'm doing wrong? The thumbnails of the main picture have been recreated without a problem. The additional image box only plays thumbnails when I open the article in the back. I do not have to save it.
