I want to use a flat panorama as the initial scene of a multires tour. So with krpano 1.17 I built the tour of spherical panos, and built a standalone flat pano. Then I copied the flat pano's tiles into vtour/panos and copied the relevant part of its xml file into a new scene in the tour xml. The tour worked fine when displayed locally, but when I first tried to open it from the web I got "FATAL ERROR: no HTML5 compatible images available!", with both Firefox and Chrome (Win7). In both cases reloading the page resulted in a normal display, and the page continued to work normally after clearing cache and/or restarting the browser.

I think this must be a bug. The xml file is attached.

Update: This error has been observed so far only on Win7 and a Droid phone; and is absent on several other platforms including OSX, iOS and some Windows versions.

Thanks, Klaus. It seems only a small fraction of viewers experience this problem, and then only once. So I shall not worry about it further. BTW great job on 1.17 I am looking forward eagerly to the final release.
