Hello, I'm quiet happy with the example of using External Methods with PIL which can be found at http://www.zopelabs.com/cookbook/1010702887 I can perfectly call this method using <img src="tumb?width=42&height=42"> and get an thumbnail in the size I want it to be. Remark: I had to use a default image name (see below) because I did not found out the correct syntax for specifying an image name. On the other hand I would like to use this external method with pages templates and I failed while having no clue to specify the parameters.s The problem is the first parameter def MakeThumbHi2(self, image="bland.gif", width, height): ^^^^ self. I really have no idea how to put this into the correct syntax from page templates. When reading the Zope Book I noticed that the examples are exclusively realized using Python Scripts and these are glued in a DTML document. Is this the only way to go here to avoid the problem of specifying the "self" argument and arguments of type string? Kind regards Andreas.
