[RESOLVED] Create a new image from part of another?

[baffled_in_UK]

Hello,

As the title says, I want to automatically create a new image from a part of an existing image (ie, take a 100 x 100 selection from the top left). I know how to create a new image from another but not how I could make a selection of an image. Is it possible ?

Thanks for any help/advice.
