Do not attempt to serialize Images from params for metadata

[WojtekKowaluk]

Exclude Image objects from params dict for serialization because it will fail:

My bad. I was sure skipkeys=True deals with unserializable entities.

[WojtekKowaluk]

yes,skipkeys only ignores non-primitive keys, not values.
