At first you need to upload your pictures onto an image hosting website like ImageShack: http://imageshack.us/
You need to create your own basic account with your e-mail address and new password, but it is free.
Then click the picture and choose "Share" and copy the link and paste it to the forum. You can always use "Preview Post" option to make sure that links are working and pictures look okay
