first, get acquainted with www.zopelabs.com which has all sorts of user
submitted recipes.  

second (from http://www.zopelabs.com/cookbook/992031125 ) the proper way
to call dtml from python scripts is:

dtmlMethod(context, context.REQUEST)

# or if _ is bound to the (Script) Python in the bindings tab

dtmlMethod(context, _)

third if you pass keyword arguments to a dtml method they will be
available for use in the dtml method.  so you should call your dtml with

context..ThumbNails.deletePhoto(context, context.REQUEST,
hidden_photo=hidden_photo, photo_name=photo_name)
