There is no EDIT button on the Images & Multimedia page for the FREE version of our app Sir Hoppity: Challenge of the Dragon.
Oddly, the edit button is present on this tab of the paid version of Sir Hoppity: Challenge of the Dragon. It is even present on the Availability & Pricing tab for this same app. Just not on the Images & Multimedia page on this specific app.
The two screenshots below show the top and bottom of the Images & Multimedia page.
Same issues on Windows 8.1 + IE 11 and on Apple OS X running Safari 7.0.2
