I have an image on my computer that I want to use for my sig pic. But when I try to upload the picture, it only asks for the URL. It doesn't give me the option of uploading from my computer. I got this image from a friend and he forgot the webiste that the picture came off of. So how do I get this picture a URL? I tried flickr but it's not giving me a URL for it. When I put in the URL of the picture's page from flickr, a box with a red X comes up in the sig pic box. So how do I get this picture into my sig? I really need some help. Any help would be much appreciated.
