You just need to register at a place that hosts images for free like Photobucket where it's easy to upload images. Once uploaded they even provide you with the code to post it in forums. The only problem with that is you're only given so much storage space, and once full, it will delete your older files to make room for new ones. Then those older files will appear as lovely red X's wherever you posted them. So I pay the $25 annual fee to avoid that with my Photobucket images.
