its a really good program, especially for those who need to look further into pictures they see.
sadly, its been causing websites like youtube to load super slowly as of late, and i did pinpoint it down to this addon. if this were to be fixed, and youtube doesn't lag to the point where you can barely add videos to watch later list, and it takes 40 seconds to load up your subscriber/home page. then it would've been an easy 5/5 for me.
