Ross,
with internet site usage, comes responsibility. You must be the owner of the image (hosting it on your site) in order to go placing it on other people's sites... and THEN only if that site's admin says it's okay.
This is because it's very, VERY expensive for bandwidth.
I appreciate your enthusiasm, but you need to chill a bit and start ASKING whenever you want to do something.
For instance, when I made my smilies page, I told people on this site it's okay for them to use them HERE... and if they want to use them on other sites, they NEED to ask both MYSELF and the site (they want to use them on) admins!
We still have fun... but we also ask!
This isn't a biyatch-out session, just a friendly reminder!
