If there is a small image in one panel (e.g. 200x200) and a big image in the other panel (e.g. 2000x2000), the scroll bars for the big image don't work because they are synced with the scroll bars of the small image (even if the small image doesn't have any scroll bars).
Need to add extra check: if original and processed images have the same resolution, sync the scroll bars, otherwise don't and let them be independent
