nah doesnt matter..
i run a mac and pc ..
upload your picture to somewhere like
http://photopoint.com or e-mail them to my ill upload them for you but they better be worth it..
then after they are on the 'world wide net' hah..
get the url of the image in example if you image is called wak.jpg and upload it to photopoint it will be somehting like
http://photopoint.com/bahbah/wak.jpg
then you use that url and type this without the spaces..
[ img ] the url [ / img ] that waaala you posted a pic..
and if its too complicated it you shouldnt be posting pics
