Add a photo.

Similar to pwg.images.addChunk + pwg.images.add, but simpler and better suited for Piwigo 2.7+


This method requires authentication with an administrator user.

This method requires an HTTP POST request.

This method also requires a pwg_token (session valid key).


Important note: we are uploading a file, so the HTTP request encoding must be set to “form-data”.

image /path/to/file.jpg mandatory the uploaded file. JPG or PNG files only.
category 123 mandatory the identifier of the destination category, use pwg.categories.getList to find existing categories
pwg_token verylongstring mandatory this is a session key, once identified you can get it with method pwg.session.getStatus
chunks 12 optional number of expected chunks
chunk 0 optional current chunk number, from 0 to chunks-1
name A nice title optional the title of your photo, don't make it too long (use the comment to go into details
name A nice title optional the title of your photo, don't make it too long (use the comment to go into details
level 2 optional (default = 0) privacy setting. See an example in your Piwigo on screen Administration > Photos > Add. 0 is for everybody, 8 is for admins only


Here comes a full example in Perl language (see the most updated version on on source code repository):
