ah it got screwed up, but what you do, is once you have the picture hosted on another site, you click the button next to the '@' sign that says "IMG" and put the link in the pop up window.
OR
you can just type [/img ] and put the ling in the middle. and of couse, take the space out from between the g and the bracket, i just did that so it wouldnt form into a link like it did before.
clear as mud?
