Nav downloads a low-resolution proxy version of all the images open in Photoshop, which you can then tote around with you when you disconnect. On one hand, it seems like a clever end run around Apple as a relatively easy way to get photos onto an iPad; it can handle up to 200 images. But it doesn't stash them in Photos, and if you reconnect to Photoshop and they're not open, it syncs them away. When you double-tap on an image it displays really basic metadata: size, color space, and bit depth. All it did was make me wish the SDK could drive Bridge or Lightroom as well as Photoshop.
