You could preload all your textures in __init__() and then iterate
over them in new_img(). For example:
def __init__(self):
self.images = itertools.cycle([image.load(img).get_texture()
for img in ['image1.png', 'image2.png',
'image3.png']])
self.img = self.images.next()
def new_img(self, dt):
...
self.img = self.images.next()
However, the problem is really already solved for your by pyglet.
There are better ways to do what you're trying described here:
