???

I try it again:

Using the example expression as Action condition makes sure that the 
Action is only shown for 'File' and 'Image' objects.

Adding a new portal type 'Foo', the condition will be false for 'Foo' 
objects.

If we want to show the Action also for 'Foo' objects, we have to modify 
the expression like this:

     python:object.getPortalTypeName() in ('File', 'Image', 'Foo')
