Use the read/write access to directories to your advantage. Do not just dump files or images into a directory. Rather, create subdirectories as needed.
For example, in the activities directory you can create one subdirectory to place images for destination rides and another subdirectory for images for dealer events. It's clear to you, and to others, what the different directories are for.
