Welcome on board mate.
To add images to a post...
First sign up to any image hosting site (such as Photobucket, Flickr, Dropbox etc�) and upload your pictures. Once you have your pictures hosted on line, they each have their own URL (web address) which you can then link to in a post/thread.
All you�ve got to do then, is click on the "insert image" button (from the toolbar) when creating your forum post and paste in the direct link (URL) of the hosted image you want to display.
