In the fact section:
"Can I post images?
Yes, images can be shown in your posts. If the administrator has allowed attachments, you may be able to upload the image to the board. Otherwise, you must link to an image stored on a publicly accessible web server, e.g. http://www.example.com/my-picture.gif
. You cannot link to pictures stored on your own PC (unless it is a publicly accessible server) nor images stored behind authentication mechanisms, e.g. hotmail or yahoo mailboxes, password protected sites, etc. To display the image use the BBCode [img] tag."
Basically, you upload photos to photobucket or flickr. On photobucket copy the IMG Code. You can hit preview before submitting to make sure the picture posts.
Just put your cursor on the picture in photobucket and you'll see the codes below the picture. But, I'm noticing that you may have to resize the pictures before posting them here.
