I have a system.
When it comes to the photos I use on this blog, I have a simple system in place to help me avoid re-using the same photo. When I use a picture and finish the post, I'll simply move the archived picture from it's original spot in "folder A" to "folder B"--or I might just delete it, depending on the photo. Obviously, I know that anything in "Folder B" has been used by me already and therefore should not be used again in another post. It's a simple but effective system.
When I remember to do it, that is.
The system works best when I finish up whatever post I'm writing and then move the photos right away. Too often, though, for a variety of reasons, it doesn't get done right away, and I tell myself that I'll do it tomorrow. And then another day goes by, and another, and--well, it doesn't get done. And then, weeks later, when I'm preparing a post and want to use a photo from "Folder A" I wind up looking at it and thinking, "Wait a minute--did I just use this one recently?" My memory doesn't always serve me well, and I don't want to spend an inordinate amount of time digging through my past posts trying to find if I've used it or not. So I wind up sitting at the computer, staring at an image, and wondering whether I should use it or not.
That's the dilemma I'm currently facing.
I have a folder with a number of pictures, and I'm almost positive that I've used some of them before--but I'm not sure. (There are some photos in the folder that I know I haven't used, too.) So, for the next three days, I'm just going to clean out the folder and post everything in there--something like 21 picture files. If they look way too familiar to you--my apologies, I probably used it before and forgot. Hopefully the other pictures that I haven't used will make up for it.
So--let's start cleaning out that folder!
