Ah, well I suppose it's time for me to post this anyway as I've been tweaking the rules for future uploads (as I did everything for the last one, and have been trying to slowly get everything fixed). The following is a modified post from the Admin forum that outlines the naming scheme:
Sure. The following only will hold for Western Ships - Golly knows more about eastern systems of naming, so would be the preferred person for setting that up.
If the drawing is representing a class of ships, then the format is <Type><Space><Class> where Type is something like DD, DDG, DDH, ect. An example would be:
If the drawing is representing a single ship, then the preferred system is <Pennant Number><Space><Ship's name> followed by an optional <Space><Year> if there are more than one version of the ship. In addition, if there are more than one drawing of a ship at a particular year, it is possible to add a single digit extension or a brief bit of text (usually a single word) on the end. The only modifications to this is if the ship is a carrier in European service, an Auxiliary ship, or a Mine-warfare ship. In these cases the type (CVN, CVA, CVE, CVL, CVS, MC, MCM, AOR, AO, AG, AK, ect.) is applied before the Pennant number. Examples would be as follows:
CV R86 Implacable 1944.png
BB Musashi 1944 Sibuyan Sea.png
This modification for carriers is put in place to allow for carriers to stick together in the lists - otherwise they would be split between the Cs and the Rs. It also allows for more explanation of what certain support ships do.
If you don't have a pennant number for a ship (such as UK battleships or Civilian ships), then the Pennant number is replaced with just the type as follows:
Last rule is for ships with MARAD hull type codes - these are much more rare (and mostly US), but are rendered with the Hull code with spaces as the breaks followed by the ship's name:

For upload sessions replacing the spaces with underscores is also possible (as for the next upload session I should be able to write a shell script to reverse that automatically).
Or at least, this is how I have been running the naming convention on the folders that I've been trying to fix. At this point, if something else is wanted, now would be the time to speak up (IE before this batch of files goes live).
This was posted in the admin forum prior to the uploads going live, and there were no complaints. I really should post this in a better and more visible place.
As for getting this done - It's long, hard, a pain in the rear, and I lost all of the work I had done on the UK folder prior to the upload. We have over 3000 images in the archive now (probably over 3500 with the latest upload session, I haven't had the time to take the backup of the new folders yet), and fixing everything takes time. If people think they can follow the rules and get me folders that are fixed, I'll consider it on a case-by-case basis. No Promises.
