### friendica/photoalbum/delete (POST,DELETE; AUTH)
#### Parameters
* album: name of the album to be deleted
deletes all images with the specified album name, is not reversible -> ensure that client is asking user for being sure to do this
#### Return values
On success:
* JSON return {"result":"deleted","message":"album 'xyz' with all containing photos has been deleted."}
On error:
* 403 FORBIDDEN: if not authenticated
* 400 BADREQUEST: "no albumname specified", "album not available"
* 500 INTERNALSERVERERROR: "problem with deleting item occured", "unknown error - deleting from database failed"

### friendica/photoalbum/update (POST,PUT; AUTH)
#### Parameters
* album: name of the album to be updated
* album_new: new name of the album
changes the album name to album_new for all photos in album
#### Return values
On success:
* JSON return {"result":"updated","message":"album 'abc' with all containing photos has been renamed to 'xyz'."}
On error:
* 403 FORBIDDEN: if not authenticated
* 400 BADREQUEST: "no albumname specified", "no new albumname specified", "album not available"
* 500 INTERNALSERVERERROR: "unknown error - updating in database failed"

### friendica/photo/create (POST; AUTH)
### friendica/photo/update (POST; AUTH)
#### Parameters
* photo_id (optional): if specified the photo with this id will be updated
* media (optional): image data as base64, only optional if photo_id is specified (new upload must have media)
* desc (optional): description for the photo, updated when photo_id is specified
* 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 setting a private photo now to public
both calls point to one function for creating AND updating photos.
Saves data for the scales 0-2 to database (see above for scale description).
Call adds non-visible 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.
Currently it is best way to inform user that updating rights is not the best way, offer a solution to add photo as a new photo with the new rights.
#### Return values
On success:
* new photo uploaded: JSON return with photo data (see friendica/photo)
* photo updated - changed photo data: JSON return with photo data (see friendica/photo)
* photo updated - changed info: JSON return {"result":"updated","message":"Image id 'xyz' has been updated."}
* photo updated - nothing changed: JSON return {"result":"cancelled","message":"Nothing to update for image id 'xyz'."}
On error:
* 403 FORBIDDEN: if not authenticated
* 400 BADREQUEST: "no albumname specified", "no media data submitted", "photo not available", "acl data invalid"
* 500 INTERNALSERVERERROR: "image size exceeds PHP config settings, file was rejected by server",
"image size exceeds Friendica Config setting (uploaded size: x)",
"unable to process image data",
"image upload failed",
"unknown error - uploading photo failed, see Friendica log for more information",
"unknown error - update photo entry in database failed",
"unknown error - this error on uploading or updating a photo should never happen"
---
### friendica/photo/delete (DELETE; AUTH)
#### Parameters
* photo_id: id of the photo to be deleted
deletes a single image with the specified id, is not reversible -> ensure that client is asking user for being sure to do this
Sets item table entries for this photo to deleted = 1
#### Return values
On success:
* JSON return {"result":"deleted","message":"photo with id 'xyz' has been deleted from server."}
On error:
* 403 FORBIDDEN: if not authenticated
* 400 BADREQUEST: "no photo_id specified", "photo not available"
* 500 INTERNALSERVERERROR: "unknown error on deleting photo", "problem with deleting items occurred"
