GIF only shows the first image, not the others #8119

What did you do?

I was going to generate gif file using images, but generated gif file behaves as static image.

What did you expect to happen?

generated gif with images moving dynamically(?)

What actually happened?

only the first image is shown, not the other images (same as png file)

What are your OS, Python and Pillow versions?

python3 -m PIL --report

from PIL import Image

test_imgs = ['./test_img0.png', './test_img1.png']
test_pil_imgs = [Image.open(test_img) for test_img in test_imgs]

test_pil_imgs[0].save(
    './test.gif', 
    append_imgs=test_pil_imgs[1:], 
    save_all=True, 
    optimize=False, 
    duration=500, 
    loop=0
)
image

I expect the gif moves sequentially. (dynamic such as test_img0 -> test_img1 -> test_img0 -> test_img1)

But the resulting gif file do not make any moves. (static - only the front image test_img0 is shown)

Hi. In your code, you have written append_imgs. It is actually append_images
