IE - how to read client image file as base64

Question

I am quite interested to know if there is a way to read local files with IE8 (as FF File API does)? I mean read an image file with Internet Explorer 8 and convert it to base64 encoding then assign it to a JavaScript variable.

I know there is a way in FF, but is it possible with IE8? I couldn't find any complete snippets showing the effect, so any useful tutorial is much appreciated :)
