Didn't Vipershark tell you that if you make another attachment, he'll warn you big time?
Anyway, to properly upload images onto the site, what you actually need to do is use an image hosting site (Photobucket and Imager are two good examples) to host the image off-site. Then, after you right-clicked on the uploaded image and copied the image URL, just hit the little image of the mountains you see above the area you rewrite your post. From there, just paste the image URL and you're good.
