Hello & welcome @JensR!
This looks like a successful removal of the bar or strap above the head. Did you want to share this or do you have a question or comment on the images you’ve shared?
Your can use gimp + gmic for this:
Thanks! I accidentaly sent it without text.
I would like advice to make it more easily and with better result. I used cloning in gimp. It doesn’t look good at a close look. I can hardly understad what cloning does. It took very much time because i accidentaly often move what i want to hide. It was difficult for me to predict in what direction it will copy texture.
Is there any tool in gimp that can be used, but is not as smart as cloning?
