easiest is probably to sync the images to the remotes instead of pushing them...
I use rclone to automatically sync images from dropbox to the rpi, rclone is very powerful and can easily be configured to remove old photos from remote which is default if you use sync.
It might be the --max-age you are looking for
example:

rclone sync /source/path remote:/destination/path \
    --max-age 1y \
    --include "*.jpg" \
    --include "*.png" \
    --include "*.jpeg"

you first have to setup rclone to access a source (I use dropbox)
