Photobucket works well because it provides all of the various coding needed to post in various sites. Open a photobucket account, they are free and super easy to use. Upload your pics to photobucket. Once you have the pic loaded, you just scroll over it and a drop-down will appear with the coding options... you can tell which one works by pasting it into this "write comment" box and then hitting the "Preview" tab. If the picture shows, you are good... if not, try another bit of code until it does.
