I don't think this will be possible, if I understand correctly.
The 'limit_choices_to' parameter simply alters the query that is used
to get the list of photos used to populate the drop down list. This
query is completely independent of which CategoryPhoto is being
edited - in fact, when adding a CategoryPhoto object (as opposed to
editing), the object doesn't even exist in the database, but the photo
drop down still needs to be populated.
The only way I can recommend is to add some AJAX that responds to
changes to the category drop and repopulates the photo drop down
accordingly. Thankfully this should be pretty easy using the 'js'
admin option.
