to add photos into your message or some public post you need first to register on some free photo sharing host and to upload your photos there. Photobucket and shutterfly are free and good hosts. After you do that it will be shown beside every picture some code-IMG script/ URL, so you'll have to copy that and past it in your message here and it will work.
Sharing pics works like that on all forums not just on Male Survivor.
Here is the link to one post where Anomalous has given those instruction to all of us:http://www.malesurvivor.org/board/ubbthreads.php?ubb=showflat&Number=394310#Post394310
I hope you'll succeed, if you'll have some problems just let me know!
