>Is there a pixel limit?
But there is an image scaling so they won't take too much space in the browser. This shouldn't effect posting.
Maybe there's some underlying technical cause which can't be helped.
What you mentioned are quite large images. Two possible solution:
1. scale them down;
2. cut them up into pieces and post them as separate images.
