Check if images is a list of images or a single image

To check if `images` is a list of images or a single image, you can use the `isinstance()` function in Python. Here's an example code snippet:

if isinstance(images, list):
    # images is a list of images
else:
    # images is a single image

This code checks if `images` is an instance of the `list` class in Python. If it is, then `images` is a list of images. Otherwise, it is assumed to be a single image.
