is your file in V 13 ? I tested with FMPA 12.0V4 and Filemaker Go 12.0.8. I tested on my iPhone and when I click Go to first layout, the image is shown. The only issue I have is that there is an error about a script step <unknown> - that's why I guess your file is in V13.
Built with FMPA 13 v3
Problem seen on iOS 8 with version: Go_iPad_13.0.5
