Are there any differences between inserted pictures and non-inserted thumbnails, such as file storage size? Bonus: Am I correct in ***uming red Xs are from broken picture links? Tiebreaker: Do pictures that are stored on the H.A.M.B.'s server ever expire?
Try to size your pictures in the 400 x 700 pixel range. If your picture is too large - it just wont post. As to the red X's - they started showing up when Photobucket changed from free to paid membership and held pictures hostage until you paid.
I'm not having issues posting pictures. I was just wondering if it makes any difference on the H.A.M.B. side.
