Plupload Html5 preview after Fileselect
Plupload 2 has an image object, which you can use: https://github.com/moxiecode/moxie/wiki/Image
File.getSource()
and mOxie.Image.embed()
are the methods, you are interested in.

The jQuery UI queue widget uses this.
Here's a working example for a custom uploader: http://jsfiddle.net/Ec3te/2/
Works even in browsers that don't support HTML5 File API (yes, even IE6).
