I have seen some sigs that have a different picture everytime the page is loaded or a new post is opened. Anybody know how that is done?

There are image hosting sites that has a particular feature that'll show random images each time a page is loaded. Try finding sites that has this feature.

Then, all you do is use the image tags that is assigned once you upload your images to that site in your signature here.

I'll see if my website has that feature. Thanks.

umm..

Please stop whoring on my threads. Your input is never helpful. Thank you.
