Okay, so work is hard.
There’s no avoiding it though – Flash is going away. Less than five years from now there’d be more people using dedicated content consumption devices than content creation devices, and nobody is hedging their bets that Microsoft is going to pull through with the likes of Windows 8. So HTML5 is as close to the new “build once deploy everywhere” environment as you can get.
Meanwhile, I’ve found half a dozen ways to write a helper class to load a bunch of images, with none of them looking either right or wrong.
This transition is going to take quite a while.
