### POST api/friendica/photo/create

Alias of [`api/friendica/photo/update`](#POST+api%2Ffriendica%2Fphoto%2Fupdate)

### POST api/friendica/photo/update

Saves data for the scales 0-2 to database (see above for scale description).
Call adds non-public entries to items table to enable authenticated contacts to comment/like the photo.
Client should pay attention to the fact that updated access rights are not transferred to the contacts. i.e. public photos remain publicly visible if they have been commented/liked before setting visibility back to a limited group.

* `album`: name of the album to be deleted (always necessary)
* `album_new` (optional): can be used to change the album of a single photo if photo_id is specified
* `allow_cid`/`allow_gid`/`deny_cid`/`deny_gid` (optional):
    - on create: empty string or omitting = public photo, specify in format ```<x><y><z>``` for private photo
	- on update: keys need to be present with empty values for changing a private photo to public

#### Return values
