Pictures deleted after re-naming them in Basecamp?

I have a traverse and waypoints marked with names like 12A, 12B etc..

I had been taking pictures to go along with the waypoints and wanted to re-name them to match their waypoint counterpart. ex. 12A: Higginsville, 12B: Sh below Higginsville

After changing the name the pictures disappear and are nowhere to be found in any folder or on the Garmin itself. I am using an Oregon 650t.

This is important data and I really need to get it back.
