Attaching files depend on if you're getting it from the web or not. If you're getting the image from the web, just right click on the image and go to properties. Then highlight the web address of the image. Then post the entire address between --- [/img.] (without the period). If you want to attach a file, first make sure you have it on your harddrive. You can attach files at the bottom of the 'post reply' window. Right after the heading options there's something that says "attach file". Then hit submit reply.
