Converting byte[] into an Image object

@ Kortestanov: How exactly would C# know that the image has alphas? Just tell it it's a PNG or something?

I'll get to tinkering around over the next few days.

The "Image" or "Bitmap" object automatically supports alpha (it's not a real alpha, though. You'll notice if you try working with clipboard and backgrounds). If the bytes you are supplying contain alpha information, it will automatically be parsed.
