Break it into smaller tasks, until each is doable.
The rsync command is very useful for copying and moving files. It has many
options, and so will take some time to become familiar with. Its core usage
is like the "cp" command:
rsync stuff... destination
which copies the stuff into the destination.

Ok. Let us suppose your photos are in ~/photos and the SD card is
mounted as /mnt/sdcard. These paths are entirely made up and will depend
on your setup. Assuming them, though:
rsync -av --ignore-existing ~/photos/ /mnt/sdcard/
should do a rough approximation of what you ask.
test it like this:
rsync -n -av --ignore-existing ~/photos/ /mnt/sdcard/
That "-n" means "no action"; rsync will tell you which files it would
copy, but copy nothing. Remove the "-n" option when you are satisfied.
That presumes I understand what you mean by the phrase "all the while
ignoring the new photos". I'm guessing you want to add your main photos
collection to the SD card so it can be inserted into the picture frame
for display, but not to damage any photos already on the SD card.
The subdirectories thing is trickier, and I suggest we tackle it later.
Cheers,
