Date of picture is not always shown

[skorbut]

What steps will reproduce the problem?

1. Open in JOSM the Mapillary sequence in which ​http://www.mapillary.com/map/im/XGIrTPPyCzzCxv2Bzf81kw is contained
2. Click some of the pictures

What is the expected result?

All pictures should display the date of creation in the window title.

What happens instead?

Not all pictures display the date of creation.

Example displaying the date: ​http://www.mapillary.com/map/im/G7Ej5PnZzHvQWRcEDj_W0w
Example not displaying the date: ​http://www.mapillary.com/map/im/_dqRvN-7wfS4r2CrtLJKrQ

(see also the attached screenshots)

Cause for this behaviour may be that the images were generated from a video using Mapillary's video upload feature.

Please provide any additional information below. Attach a screenshot if possible.
