You are not using the Kohana image and upload library properly. The docs have some examples on how to use the Kohana image upload and resize library:
Upload and resize
Cropping Profile Images
Docs on how to use the image library
You can resize and save an image with to following code:
Image::factory($filename)
->resize(300, NULL, Image::AUTO)
->save($your_save_path);
