Variable Image

Is there a way to place an image on the page that works off the following information.

All images are located in the 'c:\Graphics' folder.

The image names are 'Generic Door####.bmp'.

The '####' is a Field name of {Doors.Door Num} this a number format.

Example {Doors.Door Num} = 186 image Generic Door0186.bmp.

So I would get the {Doors.Door Num} place it a formula and the image would be retrieved.

Is this possible?
