[reportlab-users] Using images in body of rlzope.py example

[Dev Sen]

I guess a more general question related to this would be how to replace
"self.getImageFromZODB("logo") with the appropriate path to grab an image
stored on the filesystem dependent on some parameter. For example,
"/path/images/image=RelevantParameterHere". Is that doable?
