Oh crap that's right. The power went out and your work on that image went with it.
And for thumbnails with Imgur:
http://i.imgur.com/5ZEfG.jpg
That's the image. The file location is "5ZEfG" simply add a "s" at the end of that to give you http://i.imgur.com/5ZEfGs.jpg
Wrap img tags around it and then wrap it all with url tags with the original picture link so that it'd look like
[url="http://i.imgur.com/5ZEfG.jpg"][img]http://i.imgur.com/5ZEfGs.jpg[img][url]
There'd be a "/" in the img/url end tags though
