If you have a PhotoBucket account you can easily grab the forum posting codes that belong to each of your uploaded photos and use it to post here.

There's also ImageShack where you can upload an image and be immediately presented with the code ready to paste into a post here.

Please keep pictures of a reasonable size. 800 pixels wide by 600 pixels high is usually enough to show whatever you need to without having your picture scroll off the side of other users' monitors.
