I'd post a picture, but I don't know how.
1. Host your photo e.g. Photobucket.com or tinypic.com
2. Copy the direct link (ctrl + c)
3. Click on the 6th icon adobe 'Image Link' the one with geometric figures and paste the direct link there (ctrl + v)
4. press Ok, describe it & POST!! :) easy huh?? ;P
