the easiest way to post pictures is using
http://www.glowfoto.com/userlogin.php
register, it's free, and then when you are logged in go to "upload images" - it's blue words under your log in name about center of the screen. It will bring you to an upload screen. browse just like you do to post pics in an email. Pick the size as HUGE, pick No for random views. When you are all done (you can do up to 10 images at a time) than press upload images.
After you have uploaded them, go to "view collection" or it may be "view Gallery" depending on the screen. It will now show your pictures. Under each one is a drop down menu - pick "get code", then it will bring you to a new screen that says, "generate html and bbcodes". click on that.
You need the BBCode for the DIS board, (other boards may use the html), hit "highlight text", press Ctrl C, than go to the message you want to put it into and press ctrl V. This will cut and paste the code into message.
To get another pic's code go "view gallery" again and do it again.
Always preview a picture thread before you post it just to make sure you did it right.
Don't erase the pics from Glowfoto until you are sure that thread won't be viewed again.
