no FileReader support in Safari 5.1, which is used to enable the drag 'n drop image reading.
A "Nightly WebKit" build (which is basically Nightly Safari) works though.
Behind the scenes, I'm alpha-testing a new API for mapping feature detects to browsers, so you can say what features you need and get an automated response for what browsers they'll work in. (Another lazyweb project actually): https://github.com/paulirish/lazyweb-requests/issues/39
