1) go to this site: http://photoposting.is-great.net/?i=2
2) Either navigate your files and select your photo, or drag and drop onto their box.
3) Copy and past the link from that page onto your post here (testing right now)
DONE!
I would say don't take this to other forums, because as you can see on the page, someone created it for an RV forum. But, it resizes photos to fit here, and it works, so let's use it. You can check a box to let the viewer click on your pic and see a full size version, which is nice.
On second thought, we ought to leave this one be, and use the one below. It'd be cool to make one like this one for Golfbuzz, but I don't know how.
