normally I use microsoft picture it for cropping images, but the things so damn buggy & keeps freezing up on me,, so, I am trying to crop with photoshop.. however, the problem I have is I can only crop square or rectangular shapes...
I am trying to crop an image & I want the cropped image to be a circle.. how can I do that.. can anyone help me..

thank you...
