HTC Incredible :: Broken LCD - How To Retrieve Photos From Onboard Memory

I'm trying to help my gf with a phone issue with her Droid Incredible. Her screen recently stopped working, so we took it into the Verizon store and she got a warranty replacement. We still have her old phone (it must be returned within 10 days), and I was hoping I might be able to retrieve her photos from the onboard memory.

She does have an SD card, but she only installed it a few days prior to this incident, so I assume her photos were being stored to the onboard memory prior to this.

The phone appears to still be functional except for the screen... It still rings when it receives calls (but can't answer them), still beeps for text messages, etc., and when I hook it up to a computer via USB, two inaccessible disk drives appear.

The problem, as far as I can tell from reading online, is that the onboard memory can't be accessed unless you click "Disk mode" [or whatever it's called] on the phone after plugging it in, and if you don't click this option, it defaults to "Charge Only".
