So I see loads of image issues and loads of frustrated steemians, well I have the solution. It is quite simple. Shrink the image. The issue isn't with the hosts but a steemit issue displaying images larger then the posts viewing frame.
EDIT: Thanks to for finding the real problem.... Images need to be smaller then 31.75 Kb if you want them to work right meow. A real fix to the image proxy should come soon.
