you almost have it. you are copying the wrong link tho i think. it should be looking like this.
[img]http:/.....photobucket xxxx.jpg [/img]
i got it working by taking this link for the actual pic file from your above post: http://i895.photobucket.com/albums/a...acdiagram4.jpg
and then adding [img] tag to the front of it and [/img] to the end.
