looks pretty good for someone who couldn't figure out how to put images in posts.
here's how to do it:
[img]image url[/img]
for example
[img]http://i.imgur.com/MCveVsC.png[/img] (your first image)
make sure you're putting in the image link, not a link that has the image in it. a good way to make sure you're getting the right link is to right-click the image you want to post, and click (open image in new tab) or (copy image URL) and use that url.
