Fix the double scrolbar, debug console and the button in Media Image Pop...

Go to System --> Global Coniguration ... click SELECT next do "Offline Image" and look.
The Modal box has two scrolbars (= 2 iframes), two system debug consoles inside (all together you will have three Debug consoles (the normal below and two in modal box).

Further the little button could be improved and replaced.

Apply Patch and open the modal box again. This should fix all issue.
