Michigoose, your links contain dynamic characters. Links with "&" or "?" in them can't be used. They tell the server to which you're linking to execute a server script and place the output here; in your case the script would just display an image, but in other cases, dynamic links can execute damaging and malicious code.

I think people are having good luck with a place called Photobucket, but either way, the link needs to be static. It has to look something like this:

No question marks or ampersands.
