Access-Images

How do I (or) does anyone know a good tutorial or instructions on the internet to show how to make an image to show up on a report whenever it meets the criteria of a certain field? Example: I want to show my signature (which is a scanned image) on a report when ever my name appears. And do the same for my co-worker, when ever her name appears under the “Name” field, I want her signature to appear on the same report.
