HP Photo Viewer

[BNSFMike]

I have some photos labeled as followis & they appear in the folder/directory in this order.

Windows Photo Viewer does display them in the correct order.
Q12, R19, R21, S2, S6, S8, S10, S12, S16, S19

But HP Photo Viewer displays them in this order.
Q12, R19, R21, S10, S12, S16, S19, S2, S6, S8

Any idea what HP is doing?

looks like HP has a crap ordering system that ranks each digit individually..

I have to add a 0 in front of the single digit numbers to make it work. IOW changing S2 ro S02. Otherwise it appears HP looks at & compares the first number.
