Sure. You need to host your pictures somewhere. I use http://imageshack.us/ for most of my images, but I also have a few others spots like http://photobucket.com/. Go to one of those and sign up for a free account. Then all you have to do is follow the instructions to upload any picture you have saved, or that you have the url for. Once you have it uploaded, highlight and ctrl C (to copy) the url of the picture. Then you can enter that url in the window that comes up when you are making a post in the forum. After you click it, you can ctrl V (to paste) the image URL into the little window that pops up, then hit OKAY. Be sure to Preview your post before Submitting it. Good luck!
