Hi all, we run a design business and end up with photo's that we own on our hard-drive. I'm wondering what the best software is for giving each photo a name tag, without changing the name? (We need to leave the filename the same so that we can find where we bought the image, what the company called it, etc.) The ultimate goal is to be able to label the photo as appropriate.... "couples, cafe, dinner, laughing" might all apply to the one photo. Any ideas? Do iPhoto do this, and I just have not learned how to use it yet?
