My recommendation for this scenario involves a little bit of work upfront, but make updates super-fast later on.
Create a PHOTOS comp. Import all your photos into this comp. Select all layers, set their duration to a single frame, then use the “Sequence Layers” keyframe assistant to make it a single sequence of images.
In each of your placeholder precomps, place the PHOTO layer, enable time-remapping, and set it to a specific frame: 0 for the first image, 1 for the second image, 2 for the third image, and so-on.
Once you’ve done that, if you want to update the photos, you just have to clear out the old photos, import the new ones, and re-sequence them.
