Images (banners) are hosted on your servers, allowing quick loading and no errors. Many webhosting companies do not allow images on their servers to be accessed by other servers. Each member is given their own image folder where they can upload images to using the image uploader in their stats area. You can set a limit on the size of images uploaded, to prevent over-crowding. The program will only allow .jpg and .gif images to be uploaded preventing exe hacking attempts.
