Not sure, gave it a try but can't get it to work.


My getRecipeImage method returns a PIL.Image instance - what should it 
return?

It also looks like data.expr is NOT saved to the template file, i.e. if 
I save an reopen it the expression is not there.

Can you please give me a little pointer on how to use it.

When trying the above I see the following exception - probably because I 
don't use it correctly.
