HTML background image not showing when uploaded to LMS

I have a course I created that has a background image on the html page. When I run the course locally by launching the story html file the background is there just fine but when I upload to the LMS my background image doesn't show ... it isn't a path issue I don't think.

Does a different html page get launched by default when posted to the LMS? looks like there is a bunch of frames in the index_lms.html file?

Should I point the LMS to launch the story.html file by default?
