Too bad the compression of the images is super heavy, it's reducing sharpness and causing JPG artifacts, making hard to enjoy the details of your work.
Could you check if you can upload less compressed images? If the limits of the filesize on the board are too strict, we can surely help you out with some links to free filehosters.
Best,
Stephan
