I am wanting to make a picture of a keyhole with an eye peeking through it. I have the keyhole and the pic of the eye but i am not sure how to overlay them so the eye looks like it is in the keyhole. Thanks for your help.

ifthe keyhole is vector (i.e. a drawn shape) then copy the eye pic and 'paste inside' the keyhole shape.

if they are both pictures then use the bitmap selection tools to remove the inside of the keyhole and place the eye pic behind it

Thanks so much. Worked out fine.

nice one
