CMFPhoto and CMFPhotoalbum
i’ve been tinkering with these. I really like the way I can use the FTP interface to upload a whole folder of full size images from my camera and it creates CMFPhoto objects from each with a whole series of size options from thumbnail to full size, using Python Imaging Library (PIL). Once the images are uploaded you can even do transformations such as flip and rotate on the server.
A new plone based online photoalbum will be built soon*….
* not necessarily that soon
