It would be great (handier) if the Context-menu item would be "Save Image as Type" instead "Save image as" (which is also the name of the regular Save Image). "Save Image as Type" is also how it's identified in Chrome and mentioned in the "How to use". Installed version : 1.1.4

Because the Icon is White, it is not visible in the Context-Menu which is White too. Better would be to use the version as used at the top of the Addon-page in the Store
