Can I make an image attribute a required field?

I can't seem to find this in a search on the forum. Basically, with my products, you need to add at least one image with the product to your cart. I'm using "Logo Front" and "Logo Back". Is there a way to set it up so that the customer uploads at least one image or it won't let them check out? Thanks for any help.

Bumping this back up. Does anyone know if this can be done?

Currently, there isn't a test on the file upload on the Attributes to ensure that one is added ...

This is something we are looking into for a future release so that this can be controlled in a similar manner where radio buttons, dropdowns and TEXT can be controlled ...

Thanks for the answer. I'll just need to be careful about checking the customer's invoice. I'll be looking forward to that being a feature in future versions.
