sorry bout that - Hotkey was changed back to 'i' for both View Image and View Video as that is the more standard key.

Its the same hotkey as Open Image in New Tab uses, but it doesn't appear to conflict if userChrome.css is used to hide the official menu item.

edit: seems fair - added two new options to allow specifying custom action keys; reverted back to using M/E for default english hotkeys in version 3.1
