Editing thumbnail images under main product image

[astarina]

Where can I edit these please?
I've edited the images in the main body (to remove suppliers' watermarks) but in the thumbnails in the top left they still show the original images with watermarks.
Where can I edit these? And does this mean I have to edit all the images twice?

I think you are talking about Gallery images. You need to go to Product Options -> Gallery
