Image thumbnails aren't added by default on the image stop

[brousse]

Image Stop fail in webapp due to missing image thumbnail asset into tourml file.

These settings don't appear to be added by default on the Tap feature module. You should be able to resolve this by doing the following stops:

• Navigate to /admin/structure/types/manage/tour_image_stop/display/tourml_xml
• On the Image Asset field, select the gear button to the right
• Select 'thumbnail' and 'original' and then press save.
• You may need to clear the site cache at this point
