Including Photos In Database

I've got a database that tracks name/address/phone, etc for a large group of people. I've recently added the ability to include a person's photo on the forms and reports. I've done that by saving the photos with the naming convention of [firstname]_[lastname].jpg and then using VBA, the database checks to see if there is a file with the corresponding name of the record and displays the picture if so.

It works very well, but I can see where I would have some problems in the future. For example, if someone gets married and changes their name, the corresponding photo must also be renamed to display properly. And if there are any misspellings, that becomes a problem. Also, if James decides he wants to go by Jim, the photo would not be displayed, either.

I'm wondering if anyone has any other ideas on how I might accomplish my goal. I know I could name the photo based on the record ID, but that's not a good option, since I'll be handling the photos, while someone else will be inputting the contact details. So I won't know the recordID easily.

Is there some way to have another field in each record that points to the corresponding photo? Then if James goes by Jim, his first name can be changed, but the corresponding picture name could remain the same.

Is there some great idea that I'm missing that would make this process much simpler and scalable? Or do I just have to deal with the maintenance issues?

Thanks.
