ok a URL is the uniform resource locator meaning that when u type a url like an image url such as my banner
http://www.angelfire.com/alt/evilfl/...ukenbanner.gif would give u an image. A url is also a link like
www.yahoo.com
ok so the first thing for u to do is check back at the site where u found the image. make sure it still exists on there servers or wherever it is originally from.
i check out the url u have for ur images and they dont work i also tried to just go to hkgods.org and that also didnt work ....maybe hkgods.org is not active ne more im not sure but on to fixing ur problem...
u must find the correct url to the image. so if u find the image where u first saved it right click and hit copy shortcut then go to ur profile and go to ur signature and click paste and it will give u the exact url to the image....
i hope that helps u , if u need more help just let me know
