The silver lining to this bad news is that although the LCD screen of our Canon PowerShot is cracked, the camera still otherwise works. The camera is still usable, apparently, but anything that requires digital visual feedback is gone. Effectively, camera shots now are blind.
My daughter still has her Nikon CoolPix, however, and if I can ever find and install that card reader, we may use that more full-time (but really, we need to sort through her pictures, first).
EDIT: the screen is a Liquid Crystal Display (LCD), not a Light Emitting Diode (LED). As you can guess, it’s easier to crack an LCD than an LED.
