I have made all code to add the character posters to the database and display it on screen. Just name the filename like this "poster-00-00.jpg" (for collection 0 and order number 0) or "poster-03-06.jpg" (for collection 3 and order number 6).
If this is all ok I will add it to the website. After that I will be adding it to the API.

Collection 0 the default collection. If there are more collections, they will be named 1 and so on. The same for the order number of the posters.

i thought it will look something like this...

but your solution is much nicer! Really great!

Are you sure about the numbering?
Collection, Collection 1 ...
and not
Collection, Collection 2
or
Collection 1, Collection 2

Before adding to database maybe you have some minutes time for on a teamviewer chat regarding some important content questions.
There are a few things to keep in mind before.

Great! Much appreciated!
