They are quite explicit about the set of images of a bundle, but their size on the web, for example "Alien vs Troopers Bundle" is 4.9Mb size.
I recommend, for fluidity of data, reduce the size in Kb, with resolution or stop being "foolish" with this type of images...
Can I put a 5 Gb video in a post? 😀
I think that the simplest thing is to compose an image with the different elements in a jpg or webp, so as not to consume bandwidth in users...
(but... that's what I think!!!) 😀
