You're a step ahead! If you use Google Chrome as a browser you can simply add an extension and then you just copy/paste them where you want.

I always copy/paste them to LunaPic.com first and scale down to 150px for comments. Then you can just copy/paste it directly from there.

Lunapic is pretty awesome... but a little overwhelming. I'm working on a basic tutorial for that too (in the very near future). 😃
