I added some rudimentary support for multiple images per package. You can see more than one screenshot at czg07.
To submit more images, just add them to the packages SHA256 directory with reasonable filenames and make a pull request. Any resolution is ok. PNG is preferred. For example images for czg07 are in https://github.com/Quaddicted/quaddicted-images/tree/main/by-sha256/38/38ee9811a6181f4b302ded52f1eade9fa131b2f7e0de801615aa9234beb39257
Every package's page now has a "Add images" link that takes you right to the correct directory on GitHub:
If someone is CSS-smart, it would be ace to have some rules that squeeze all images that are inside a fixed size div into a smart and sexy grid. I was too stupid and used some flexbox with precalculated image widths based on the number of images. It would be ace if it could be done client-side in the browser (without JavaScript!).
