The pic is in jpg format and 781 kB but I can't post it already second day. I wrote the administrator to help me. I hope download it today
Can you convert it to a PNG file? The Forum seems to reject JPG files that my camera produces - probably because the file includes EXIF data. If I create a JPG file directly on my PC (from a drawing, for example) the Forum accepts it.
Another thing that works for me is when I cut out a piece of a camera JPG and make a completely new JPG file with the piece cut out. I use the GIMP photo editor.
