[MENTION=2894]2BullyMama[/MENTION] if you have pics set up as tapatalk hosted it will work, if you have it as attachment then it's using the site one. I am fairly sure you changed it to attachment at one point.
We will continue to try to figure out what the problem is, smaller files seem to work ok for me, but they are the ones from the photo contest- so they have been resized and compressed.
Until we figure it out, there is always photobucket- that will work.
