how to cut & paste pics?

Lets say I received an email with lots of nice pictures that I want to share here. How do I go about doing that?

Do I have to save each pic to my computer, then upload it to photobucket, then copy & paste each one to the thread? Is there any easier/shorter way for I have too many nice pics to share but too little time

Unless the photos are already posted on the Internet somewhere....
The easiest way I know is what you mentioned above.
