Hi,
I observe your Project (Zenphoto) the last days and let me ask some questions...also at the risk doing reiterate requests.

Reason for this questions:

• I will invest time in Ajax and especially in a Photo album. Till now I'm focused at
  Ajax and J2EE but why not PHP?
  It seems that Zenphoto has more potential to start with this issues from the
  beginning than others Projects(Gallery2, Coppermine).

Architecture:

• Is there information about the architecture of Zenphoto? API ? (Yes, there is a
  little bit)

Documentation:

• Do we have Docu regarding Zenphote itself and the structure ot theme?

WebGUI:

• Is it possible to create (with Ajax) a GUI like this http://f-spot.org/Features?
  With F-Spot there is a "timeline", also Tags are available and a simple Phote
  handlings.

Testing:

• What about automatic testing? There are so much Zenphote hacks and themes...without
  Testing we risk an unstable Product.

Thanks in advance...
Stef
