I would like to be able to directly paste my clipboard image into a Gmail message. I could then just do alt-print screen, go to Gmail compose and press ctrl-v to embed a screenshot, for instance. I'm not talking about embedding a image from disk into my email; that's easily done. I want to skip the step where I have to save it to disk first.
I would like to find a free alternative, or make one myself, but I have no clue how picturepaste works.
edit: I would like to have the picture inlined, instead of a hyperlink.
