Yeah the handy dandy "PRINT" key on keyboard then it´s in the clipboard,
just go open any graphics prog as example Photoshop in Photoshop say "New"
and it automartily opens a canvas the size of your screenshot and go to "EDIT-->PASTE"
Mark the relevant part "EDIT->CUT" "NEW" "PASTE" and I go "SAVE FOR WEB" as a jpg
The End. (after uploading it)
