The easiest way to post pictures is to place them in the gallery, then open them and copy the address under the photo and past it in a post.. Like this..
The line address "[ img]ttp://www.clubcobra.com/photopost/data/500/medium/RedOne4.JPG[/img ]" is in an address box under the photo. I've changed the spacing so that it will show you what the address looks like.
