Not too sure what you mean by sending pics? I'll make a guess that you mean sharing pics on the forum like others do? If so you have a couple of options. You can upload them directly to the site by going to the main page, clicking on 'Gallery' then clicking on 'upload photos'. or You can use the likes of imageshack or other free photo storage site ( google them for more info- but really easy to use )
Once you have put your pictures that you want to show you need to link them to your post somehow. That is down using some very simple code.
Example:
This one use the following code [*IMG]http://img90.imageshack.us/img90/5016/imga0377cx4.th.jpg[/IMG] and you cannot click on it.
This used this code [*URL=http://img90.imageshack.us/my.php?image=imga0377cx4.jpg][*IMG]http://img90.imageshack.us/img90/5016/imga0377cx4.th.jpg[/IMG][/URL]
and you can click on it..
Again you have to remove the * from the code to make it work.
If in doubt you can use the preview option to see if it's worked or not.. Hope that helps.
