Did you copy the IMG Code of the picture from your picture you uploaded to Photobucket? I have been using Photobucket for years and never had any issues uploading to and from unless the internet was having issues at the time.
Copy and paste the IMG Code of the picture to your posting. I will admit, I have not been on PB for a little while, and the features have changed a bit, but it still works. I just tried it out and it worked fine for me anyways.
That problem now seems to be sorted out, and yes, I pasted the IMG code, but the best I can get is a link. At least that way, people can still look at pictures and see what I mean.
