I think you have two questions. For the first, go to "View" in the Organizer. Click and scroll down and check "Details." That will separate your images and show date, time and image identity (for instance, IMG_3243.jpg). For the second, I am not sure I know what you are asking. If you mean you want to "unstack" the stacks, click on the little arrow on the right of the stacked images. Hope this helps.
Yes, you did help. I don't know how I missed it on organizer, media screen on my Elements then view. I must be getting younger and very rash? Thanks to all.
