I've accrued around 20000 images of internet randomness, and their disparate file names have finally triggered my OCD. I'm at a complete loss at a practical structure and method for batch sorting and renaming them. My lazy inclination is to rename by creation date, but after meeting people who sort their porn by color and emotion (don't ask) and others with too much time sorting their image collection by subject (i.e. img \bears \ bear tongue \beartonguelong.jpg ), I feel like I should... do better.
If no exiting program can automate this, I think I'm going to have to write or try to convince my developer friend to write a script to determine the RGB value of each picture and rename them as RGB scales so I can search them by rough color ranges. i.e. R24G10B01.jpg for all images with R240-249, G100-109, B 10-19. Maybe too much work for something like this. Either way, I'm just polling to see if there's any organization structures for random pictures I'm not thinking of.
Obviously you need to put your vacation time in with work, then start looking at the photos one at a time, and moving them into catagories(such as funny, gross, sexy, etc), then naming them based on the catagory.
That or just delete them, because really, are you going to look at them again?
