Here's how to post images here on the forums, from the BeastieBoys.com FAQ
1) Upload your photo files to a webserver if they're not already online. If you need a host find one here
2) Go to the Sure Shots forum, and post your image(s) by placing the [IMG] and [/IMG] tags around your photo URL(s).
Note that you can only post Beastie Boys photos in here
. All non-Beastie Boys photos should go in the Sure Shots
