Have any SQLfags dug into Q's jpeg and png file naming convention?
They appear to be Microsoft SQL GUID numbers. Here are the last 16 file names(sorted) of pics Q posted:

MS SQL Server GUIDs are randomly generated, however the 15th digit always seems to be 4.
Here's the format for easy cut/paste into a search engine, you'll get plenty of info on SQL GUIDs:
00000000-0000-0000-0000-000000000000
I'm not going to dig too hard on this as I assume it is random file name renaming, or pulling images from a database. It is mildly interesting why Q is consistent on naming files in that format though.
