For lots of dust type dots you can use a (compiled) plugin called resynthesizer with its associated python plugin heal-selection see: https://www.gimp-forum.net/Thread-Resynt...or-Windows EDIT: I see you have already been there. Does it not work with your images?
For spots on a photograph: You will have to imagine this one for the speckles. https://i.imgur.com/GKmKI1V.jpg While it is greyscale, easier to demo in RGB.
Bottom of the select menu is Toggle Quick Mask (shift-Q) That puts a mask over the image (default is red which does not show very well in greyscale) Using a small white FG brush, paint over the speckles. Looks like this: https://i.imgur.com/H61F8Mi.jpg
When complete, toggle the quick mask off. (shift-Q again) and there are selections around the speckles. https://i.imgur.com/84tEpx4.jpg
Start the heal-selection plugin Edit -> Enhance -> Heal Selection settings depend on what you are doing, speckles typically: small width, All around, Inwards. https://i.imgur.com/VUHe1Ng.jpg
OK it and when complete, the speckles are replaced by adjacent pixels. https://i.imgur.com/Xj5hpHw.jpg Takes a little practice. Sometimes best, missing the odd speckle out and returning later to fix. Telephone lines for example best using "top & bottom" ...
Tried the resynthesizer. Took quite some time. Maybe I did something wrong, the new image does not look as good as the original, not as clear.
Will try what you have suggested. Many thanks for your help.
Noted that it is slower now that I have upgraded from 2.8 to 2.10 (my PC is Dell Inspiron 365 with 8 GB ram). Is that expected with 2.10 vs 2.8? Sorry for his off topic.
