Frontend image resizing support

Nobody has claimed this yet.

Hello

Since performance is quite hefty when people resize huge images, i have found some nice bicubic/bilinear filters for resizing images in the frontend via canvas.

However i can only upload the image via a hidden input as base64 string (haven't found a better way without using XHR). Also i can convert the base64 to binary on the server. But is there a way to pass this binary data to imager ?

``` js
var base64Data = req.body.resized_image;
images = [new Buffer(base64Data, 'base64').toString('binary')]; // doenst work with imager
```

Start by comparing the two linked canvas examples with imager's existing image-input path; the issue provides no file or test names, so locate where the module accepts image data and how the Node Buffer is handled. Done means frontend-resized binary data has a supported path through imager, with behavior checked against the existing image handling.
