Well one day while surfing the web I came across what has to be my best purchase EVER! It's called the "Element Separator" by creation Cassell. Best $6.00 I ever spent. It's an action that separates all of the images for you.
All you have to do is drag the .jsx file on top of the images you want to separate and in a short period of time they are all separated and in a folder on your computer. On a recent letter/number product it took less than 2 minutes to separate over 150 images. What a time saver!
You do have to change the names after or you can use the ones the file creates. My customers like having the specific names of each image so I usually change mine.
If you have never used an action like this all of the directions are included. They also have a version for Paintshop Pro.
I know there are probably other actions like this out there but I'm using "Element Separator" and I love it.
