setuptools, accessing ressource files

[Patrick Sabin]

I use setuptools to create a package. In this package I included some 
images and I checked that they are in the egg-file. The problem is how 
can I access the images in the package?

I tried pkgutil.get_data, but only got an IOError, because the EGG-INFO 
directory doesn't exist.

I tried
pkg_resources.get_distribution('dist').get_metadata('images/image.png')
with a similar error (IOError)

What is the best way to access images distributed in an egg file?
