Naming booklets and drawings

Hi,
I have always found trouble naming pics.
I will give you an example:
For

Cléo de 5 à 7 (1962).mp4

I named the CD booklet images

Art-1.jpg
(there are many, which I named Art-2.jpg, 3, etc)

Sempé, an illustrator, produced material about the film. I named the files:

Sempe.art-1.jpg

I cannot see any pic…I must be doing things wrongly.
Can you please help me?
Thanks a lot,
Regards,

Best take a look at the related support article and rename your files accordingly.

Plex does not support booklet scans. Only the cover/front is used.

Thanks. Maybe it is a stupid question but reading the article I don’t understand how to simply name a picture related to the film and see it appear on Plex.
And when I give the example of the booklet images, I am not interested in making them appear as a booklet, but as pics or images. Is there possible way of doing it? Thanks,

Thanks. Sorry, I am not interested in keeping that as a booklet, but as pics, and I don’t understand how, even reading the article.

You can have only one picture appear in Plex per movie, or per music album.
The poster / cover of that item. That’s it.
There is no way to add a whole gallery’s worth of pictures to a movie or to a music album.

Oh, THANKS. That was really clear.
And for that only ONE pic, should I label it fanart?
Thanks again,

Thanks. I guess it must be .poster
