Unless you have yours wide open for anyone to view, I don't think you can. I use flickr for my pics. Unlimited storage for a yearly fee that isn't too bad. Some people use photobucket. Not sure how it works though. Never tried it.
i use imageshack (http://imageshack.us/) yup it's free....
make an account
upload your pics over there
hit the forum's "insert link button"
copy/paste the direct link from imageshack
hope this helps 😀
