They were "filed" before I worked out a system of renaming every picture as I downloaded it from the camera. Now I do this using Adobe® Bridge and I'll describe the process in case you need a system for doing this.
Above: Here I've inserted a memory card from a camera and navigated to it in Adobe Bridge. I've highlighted the pictures that are of the same place because I can give them the same name followed by a number.
In this case, I put them in a folder on my computer that I created for the current month. If they were for a particular website other than my blog, I would use a special folder for that site.
P.S. You can search from Bridge and see a display of pictures found.
