I would like to announce a small tool I hope the community can find it useful for developing gallery plug-ins.
Pulse Photo Interface
Easly create a gallery plug-in based on Pulse Photo functionality (back-end uploading, re-sorting and captioning) with this interface that provides php sorted arrays of photos and captions.
I successfully used this interface to implement two new Pulse tags
They are both available for the community on a dedicated web site,
Each piece of software is open-source so you are all welcome to improve.
