I can, but that requires me to run the whole collection through a special script to change them, and future updates would be very hard to handle, so I am figuring out how customized posters could work.

I did add a third option to the site last night where you can purchase a pre-loaded USB drive with all 10K current posters and music, but no updates as a few people asked for it already.

Customized could probably only work for physical media options, but without updates. The current collection already goes into 2023 and even has some 2024 movie posters, and already contains every popular ever released up until now.
