My goal is to tag photos in digikam and then automatically sync them into piwigo smart albums.  I.e. dump from camera, tag with digikam, run script, tell friends/family that the new photos are visible in piwigo.

I figured out the piwigo schema enough so that a python program I wrote can:
* Find all images newer than a time/date (of the last sync)
* Identify those with 5 stars for publishing
* Look up the tags for the new 5 star photos
* Eliminate the digikam specific tags unlikely to be useful to piwigo
* identify the directory and file name on the images

Alas, I didn't realize till just now that pwg.images.addSimple is restricted to JPG/PNG files.   I found pwg.images.add but that seems a bit more complex than I'd like since I have to scale/supply multiple copies of an image.  Is there API access to the same functionality available through piwigo -> admin -> photo -> add?  I think that it takes NEF and JPG and handles any rotation/scaling necessary.

I was looking for API documentation but if I go to:
   http://piwigo.org/doc/doku.php?id=en:de … images.add

Then click on webapi I get page doesn't exist.  I was hoping for a function that would allow me to:
1) upload NEF or JPG
2) allow me to provide tags
3) would handle any re-sizing, thumbnails, multiple resolutions, and rotation

Oh, and one more closely related question.  Is there API access to allow changing the tags of a photo?  If I add/remove a tag for a photo my script can detect the changed modification date in the metadata... but how do I tell piwigo?  Normally I'd read the (missing) API docs.
