I moved this becasue where you originally posted it was off topic...now it's it's own topic.
Image size restrictions are an issue for me at times as well. With PNG's I have found if you convert them to a palette with only the essential colours used they can sometimes fit but not in the case of that one you posted to onedrive. The ones Aeraaa posts for his AAR's are WAY bigger than the 73.2 KB that Shrapnel reports as being the max size for a PNG yet they are being displayed. I am told that should not be happening.....yet it is
and that link you posted

works for me. I can see the image
I have referred your problem with contacting customer service directly to Shrapnel. I have no answer for that, it will need to come from Shrapnel
