Here you will find images dating from May and June 1940 and which can, because of their caption, can be tied to a location or date. 

1. Crossing of the Meuse at Monthermé, May 1940  A nice example of a German 16 ton pontoon bridge.
2. France May 1940: refugees passing a German column
3. German Pak in Rotterdam May 1940

More images will be added as I get them and have time to scan them.
