Hi, jjosa!
Never been faced with such issue, so let me think while writing.
You got the image in the clipboard yet, first step ok.
Now how do you move that image to an image control on a userform? The only way is thru the Picture property and the LoadPicture statement that needs a file name with full path.
So the problem is how to generate that file... There are APIs (application program interfaces) that handle clipboard contents... Let me see...
I found them, but why reinventing the wheel? Give a look at this link:

But it doesn't work (it actually hangs badly) in Excel 2010. Maybe it helps you, if I find anything else (or the time to build access to clipboard and copy image) I'll post again.
Good luck.
Regards!
