A single file of images will be difficult to use. The photos must be sorted and filed into a set of logical folders. However there is no right or wrong way to sort and file the photos. If you take photos every quarter then you may want to compare images over time. You may want all the photos from each location filed together.
You will need to decide if you want to rename each image.
As you can see filing the images will require a lot of careful consideration and quite a bit of work.
Note - How will you download your images?
There are many programs that can help you download your images. Make sure the way you download images will not prevent you from sorting, renaming, filing and sharing images. Some programs can make it nearly impossible to share your sorted and renamed images. If you have a program that requires the use of a special program to see the images as you have filed them, do not use it.
