resizing without a black fill

[eluser]alphane[/eluser]
I had this a while ago when I ran the resize function twice.

It's a result of the image being resized once, then resized again immediately. It occured when I didn't realise that doing a result check also ran the function.

I'd check and ensure that

Code:

$this->image_lib->resize()

is definitely only being issued once.
