Open image in your favorite Photoshop/Gimp/Whatever, mark a 
circular-shaped area, invert the selection, cut away (make sure your 
current layer allows for transparency; e.g. in Photoshop you may need to 
duplicate the layer first, then discard the background layer).

Export the image with transparency (aka alpha channel), and you're there.
