Hi G.,
MS doesn't provide tools within Office to crop non rectangular areas, but graphics programs may have the capability to either crop
or 'frame' a graphic with a shape.
In Office if you insert an autoshape of a circle and then use, from the drawing toolbar, the Fill icon and choose Fill
Effects=>Picture you can insert a picture in your shape and have it fill that shape.
Sometimes it works, sometimes not, depending in some part on whether the graphic is actually large enough to overfill the circle or
star, etc without leaving 'white edges' showing.

I have a picture taken and want to crop a circular part of it, i.e. to have a
circular picture that I can embed in other documents. How can that be done?>>
