The first part of the question: I've got a Google Glass device and I plugged it into the USB port. The drivers install fine on my WinXP. I do see the Glass directory pop up in My Computer. I'm able to take a picture, as well as copy it to my PC. However, how do I copy or upload a picture to the device? It does not allow Paste. Right-click -> Paste option is disabled. Dragging a file also doesn't work.
The second part of the question is how to view all images on the Glass device, with something like VLC APK?
Update: A workaround that I've found is to share images/videos from another Google+ account to your Glass device Google+ account. This seems to be the easiest way so far that I've encountered.
