We sent all of our old photos in the old slide trays.
Digmypics kept us fully posted as they processed our slides and the final selection of which slides we wanted to keep was painless.
Everything was returned along with the digital pictures on a cd.
I was able to quickly copy the digital files to my hard drive.
It was joy to see some of our old family pictures that I have not seen in 45 years since our slide projector broke.
