Permamently criopping a photo

Morning all

Apologies if this is a really stupid question - is there a simple way of permanently cropping a photo?

Currently when I apply crop it looks as if the photo is cut, but as I understand it the rests of the photo is still there but not visible.

This is fine in most circumstances but when I add it to a gallery the rest of it appears.

Many thanks in advance!

Right-click and select "Create bitmap copy...."

Boy - thank you for the quick and helpful response - it works!

THANK YOU!

be aware if you use are using photos that are not 96dpi you may need to change the bitmap copy resolution accordingly
