Gallary wallpaper problem

[Juddz]

Hi peoples i have a really noob/dumb question and it hurts that i even have to ask this, for some reason i cannot figure out how to use a gallery picture for my home screen scroll pic, every time i click on the option "set as wallpaper" all i get is a crop tool that only wants to crop vertically and not horizontally, in my Gallaxy SII i had the option for either? Thanx in advance for anyone who takes the time to read or reply to this question. Cheers.
