While I know I can tag JPEGs by putting information into the EXIF there is no app that can decode that my dog FIDO is in the picture and add that tag for us.
There is no such app today.
I take a lot of photographs and have devised my own filing system that works quite well for my purposes. My OS is XP, but I am looking for a very simple program or software that only needs to tag and then retrieve tagged photos on command. Does anyone know what might fill the bill - free or paid, doesn't matter. Just need the technology. Thanks.
