upload files and graphics

Are there any upload controls that would be able to use the cut and paste function?  I would like somebody be able to do a cut and paste (or more specificaly a print screen) and paste it into the message?

Also, I noticed that if I add a picture and it is larger then the edit box and I then go and preview it, the edit box does not adjust in size but the picture hides the post buttons.  you actually have to move the picture out of the way of the buttons.
