Unreal Engine 4 is available for Win10 UWP app dev now

Just this information right here is incredibly helpful, thank you for getting in touch with the team and gettings this together.
So far, so good I would say but for one issue that I’m facing (perhaps for lack of knowledge.)

Illustrated below is the UWP page mentioned in your post above, when I attempt to set the images using the usual method I am unable to select any images that I have prepared in any format.
The only format in the drop down is “(*.)” .

Is there perhaps a different method for setting these images ? Or a particular format that is required ?
