I should be able to paste an image URL on its own line and have it automagically embed.
Maybe this should actually be oEmbed support for more services through Jetpack?

<img src="http://bios.weddingbee.com/pics/148769/Lolcat7.jpg" />
I'd recommend using wp_embed_register_handler() to do this. Just have a low priority (high number) and match known extensions.
Add an image URL handler
Converts lone image URLs to image tags.
@Viper007Bond thanks for the pointer, it saved me lots of time digging around.
