The names of the images contain a lot of information,
including the current position of the frame in the hive,
and the date the photo was taken. The names of the files
are set up so that when the computer displays the list,
they are sorted in the same order that they are in the hive.

The hive boxes are numbered from the bottom up, starting with 1.
Frame slots are a, b, c, d, e, f, g, h, i, j.


An image name might look like this: 12c1_1.2.02b_20170806.jpg

"12c1" is the position of the frame. It means: hive #1, super #2, frame slot c, side 1.

"1.2.02b" is the name of the frame. (I originally named the frames after their position,
but later realized that I need to move them around sometimes.)

"20170806" is the date. Year 2017, month 8, day 6.
