If the photos are on another web site, do the following:
1) Right click on the web address, it will get highlighted. Then click "copy" in the box that shows up.
2) When you go back to replying in a thread here, right click where you want to put the link you copied and hit "paste". When it appears, sandwich the address/link with
[ url ] and
[ /url ] (No spaces in between anything, including the address/link.. The spaces I put are the only way I can make it show up!)
The address/link will end up like this:
http://classracer.com/classforum/index.php
Hope that helps.
