I don't understand why this photo name thing is a "me" problem anyway. Computers are great at repetitive pattern replacement tasks like this. Just fix the survey and app so they name the photos as they are uploaded. There's no consistency here anyway, as they have not actually effectively defined what they want in there for things like "type" and "city". Or even the picture type at the end for that matter.
Everyone has their own abbreviations for the type. I've seen REG, reg, hazmat, HAZ, and many others all used on the forum. And for city some are using zip code and some are using some abbreviation of the city name. With just thirty characters to work with, there's no way abbreviations will be avoided. LA is an abbreviation not the city name, albeit a commonly understood one. When I do the shop you just did in a couple of weeks, my chosen abbreviation won't match yours. They think they are going to get consistent file names but they are not. So really, we're all just marching around in circles for no net gain.
