How to add an image?

hey folks, how does one add an image of your item for sale to your post when adding a new topic to the classifieds/for sale section here?
Tired the insert image thing, but no luck!

You’ll have to post the image on an external site like photobucket or whatever, than paste the link to it between [img][/img] codes.

i see, thanks!

Has anyone figured out a quicker easier way to add images?
