Image Manipulation Class - Resize Original AND Create Thumb???

[eluser]Muppit[/eluser]
According to the docs:

$this->image_lib->resize()
The image resizing function lets you resize the original image, create a copy (with or without resizing), or create a thumbnail image.

it would seem the image manipulation class won't actually resize the original image, AND create a thumbnail from it??? I've tried using various options with no success.

Is this correct? In which case, I'd have to resize the image and create a thumbnail from it, then go back and resize the original without creating a thumbnail...seems like a seriously roundabout way of doing it.

Is this right or am I missing the mark?
