I get an assertion error here.

Right, 'zope.app' is the mother package of all packages that are 
specific to the Zope application server. Since Photo is not such a 
package and even depends on third party libraries (PIL, imagemagick), 
the convention is to put it *outside* of Zope, simply as a top-level 
package. That means you can put it *anywhere* you want in your Python 
path; recommended is $INSTANCE/lib/python.

The ZCML slug (photo-configure.zcml) would then simply read:

   <include package="photo" />

Examples for top-level packages that are Zope applications are:

- buddydemo (http://svn.zope.org/Zope3/trunk/src/buddydemo)

- zwiki (http://svn.zope.org/Zope3/trunk/src/zwiki)

- z3checkins (http://svn.zope.org/Zope3/trunk/src/z3checkins)

Ctrl+C when running runzope. zopectl stop when running the zdaemon.
