Google has made it pretty easy to embed 360-degree panaroma shots (called "PhotoSpheres") from Android phones directly onto your own website through the plusone.js api
A very basic example is:
<html>
<head>
<script type="text/javascript" src="https://apis.google.com/js/plusone.js"></script>
</head>
<body>
<g:panoembed imageurl="https://lh5.googleusercontent.com/-kr97Eucg6sM/UKGEuvo_eBI/AAAAAAAAi0s/adq8uqyhm_k/photo.jpg" fullsize="4096,2048" croppedsize="4096,1380" offset="0,480" displaysize="600,400"/>
<script>
gapi.panoembed.go();
</script>
</body>
</html>
However, this ONLY seems to work if the image passed in imageurl is hosted in Google+. Is there a way to use these images without first giving the image to Google? I take the panorama on my Android phone and can view the 360-degree magic on my device with no problem. I copy the image off my device and upload it to my web server, however if I link to my own copy of the image, the "magic Google stuff" does not happen. If I then upload the image to Google+ and then view it and get the URL and paste that in...then it works perfectly. I would sure like to skip the Google+ step and just use my images without giving them to Google.
Any idea how to get this working on images that are not Google hosted?
