Alright Eric I think I can help you out. Right click your picture file in the gallery section its on the end under the file category; and copy the url address, then when you click the add image button for posting, push the delete key to get rid of the http:// that appears by default, if you don't delete it and you have copied the whole url address you will have two http:// which will cause a red X, then just paste the address and it should work.
Sorry I had the picture posted for awhile. I just realized you probably wanted to post it for yourself in another thread.
