Library Listing Image Dimensions Vary - CSS Fix?

[Scrat134]

Hi n00bcodr,

The stats...

Jellyfin v10.11.2 (recently updated from v 10.10.7)
Synology Container Manager / Docker (No Mem Limits / Med CPU priority)
Synology DSM 7.2.2-72806 Update 4, Intel Celeron J4125 2GHz, 18GB RAM
20TB HDD NAS Storage (RAID)

The conundrum...

I use Jellyfin to manage a number of libraries of varying size. I use the "Home videos and photos" content type for all of these.

I've noticed that on the iOS app and on the web, despite all of these having the same image type selected for the file listing pages ("Poster") they all show different sizes, which essentially overrides this selection.

Within each individual list all poster are the same dimensions (unlike the Android TV version, but that's a different story...!) but many of the lists show a different size across all files within - some library directory lists display wide rectangular images, others display square images, and some show the poster sized images as expected.

My setup is:
Library 1
Library 1 > Subfolder A
Library 1 > Subfolder B
Library 1 > Subfolder C

Library 2
Library 2 > Subfolder A
Library 2 > Subfolder B
Library 2 > Subfolder C

Etc.

I can't see any obvious way of getting these showing as expected (ie: all "poster", vertical rectangle images).

Example images attached showing example screenshots from iOS app and web:

• Poster sizing - as expected (both web and iOS app)
• Wide rectangle sizing - unexpected (both web and iOS app)
• Square sizing - unexpected (applies to both web and iOS app, but missed screenshot for iOS, so only web shown)

I understand that there's some sort of backend logic in JF that varies the sizing of these images... However, I really don't like how this makes the front end look.

There doesn't seem to be anything out there right now that can 'force' listing page images to be 'poster' type images...

Is there anything Jellyfin Enhanced could do to achieve this? If so, I'm pretty sure it'd be unique!

Many thanks!
