+In the options object, you must set the numbers of `frames` and an `imageURL`. The `imageURL` is a function that
 takes an
 index as a parameter and returns a string representing the URL of the image at that index in the sequence. This allows
 you to dynamically generate the URLs of your images based on their index in the sequence.
