Have you tried looking at them not in Photo Viewer but in some other program before uploading?
The generic sRGB profile is basically the right one / the standard for things on screens / the internet.
That's what I thought... and yeah, they look correct in Paint, Photoshop, the Photos metro app. And apparently a png or jpg screenshot of the photo will upload and look correct on say, imgur. Just not the exported jpg. Argh
