Edit my image to fit into Mt Rushmore picture?

[sidalam]

I have an image of myself and a picture of Mt Rushmore with faces of the American presidents.
I want to edit myself so that my image fits uniformly into the picture of Mt Rushmore. At the moment MT Rushmore is in stone effect. How do I edit my image which is in full colour to a stone effect in Fireworks.

Thank you in advance?

Select the picture, and I believe you can add a texture to it-- should come up in the properties window...
