Kathy, it is a cumbersome process to do it by hand although it is easy (just annoying). That is why I coded this script to do that faster. It will separate each element in separate images, although you would still have to name and save them manually. On the other hand, there is also a way to keep only one file, but separate those elements in individual layers, and also, there is a script for that. There is a video in the description.
