You should look into getting your self a free Photobucket (or equivalent) account to host your pictures. Check out the "Forum Help & Suggestions Center" (bottom most forum section) for a thread entitled "Image Posting FAQ". That will explain everything you need to know for posting images on the forum with some specific things discussing linking to photobucket hosted images for better bandwidth control and page load times.

Or else, reduce the dimensions or quality of the image in order to get it to fit within the limits.
