After copying the url, paste it between [img] and [/img]

so it looks like this...

[img]http://www.themogh.org/cg_pix/nv/38919.jpg[/img]

click on preview, and you should see your picture ...then click the "post" button. If you don't see the picture, try again (we all had to learn it! ) .

(Much easier if you can see the formatting, rather than trying to explain it with quotes, spaces, and explanations )
