all our cats are photgraphed for the web. I have a strict computer file order so cats needing homes are on my D drive
ccg/homeswanted/1234 fluff/ where 1234 is the cat number.
each cat then has its photos stored in there and any notes i want to make on it.
when they are homed i move the directory (usually when i remember!) to ccg/homed/..... so that its still all there for me to access if i want/need to.
It works as long as there is no confusion over cat numbers!
