One more question. I started adding more of the photos for the waypoints on the RP50/100 map. The photos have been uploaded to a File Cabinet page in our RP google sites site. This works as expected in the ArcGis Online viewer with the pics displaying in the popup, but when I open in ArcGIS Explorer online, the photos aren't showing - just a red x. I put the url in the Media part of the popup. (I've also included the Photo url as a field on some tries, so a person can get the original photo. Exploring options.)
This worked fine with the original photos. New photos are the red circles, old stuff was the green square pins. The only thing I've been able to think of that's different is those first photos were grabbed from my personal website (not a google site), and these are from a google site. The size of the google sites photos might be larger (800x600?) while the first photos were more thumbnail size (400x300).
thanks.
