In addition to custom tags, photos must be put into predefined categories. With this feature, it can be possible to fetch all photos of all OpenPhoto users in a category.
To be honest, I don't see this making it's way into the core system. Perhaps something which a plugin could be created for?
No. What I want is to create some categories and force users to select one/some of them for each album. One may create albums like "Summer Holiday 2012", "Skiing in the Alps February 2009". These albums can be categorized into the category "Travel". Or an album called "May Day Rally in Chicago" must be categorized into "Social Events.
Then, I will collect photos of all users in a particular category using the API.
Some categories in my mind are:
- Social Events
Albums don't solve this need?
