To add a picture go to an image hosting website [ I always use this : You are not allowed to view links.
Register or
Login ],
select your size ( choose 640*480 for message boards ) and upload your image there, you'll get a link
look for "direct link" and click on "copy to clipboard" (circled in red)
then on this forum, click on this tiny monalisa icon
paste your link between the "img" tags.
thats it. your image will appear.
