[Plugin] Jellytag

[Atilili]

I made a plugin that automatically adds quality resolution badges to your media posters, thumbnails, and backdrops.

How it works: The plugin intercepts image requests server-side via HTTP middleware, detects the video quality from metadata, and composites the appropriate badge onto the image. No client-side configuration needed, badges appear on all clients (web, mobile, TV, Kodi).

Features:

• Automatic quality detection (4K, 1080p, 720p, SD) from video metadata
  
• Works on all Jellyfin clients without any configuration
  
• Configurable badge position, size, and margin per image type (posters, thumbnails, backdrops)
  
• Choose which quality badges to display
  
• File-based image caching for performance
  
• JPEG quality control
  

Installation:

1. Add the plugin repository in Jellyfin: Dashboard → Plugins → Repositories → Add

• Name: Atilili Plugins
  
• URL: https://raw.githubusercontent.com/Atilil...ifest.json
  

2. Go to Catalog, find JellyTag, install and restart

Requirements: Jellyfin 10.11.x or later

Tip: If you have separate 4K and HD libraries, JellyTag pairs nicely with my other plugin https://forum.jellyfin.org/t-plugin-watchsync which syncs watch history between them. JellyTag lets you instantly see which version is which, and WatchSync keeps them in sync.

Thanx a lot for your work.

Hi would you be able to do this for server 10.10 also ?

[Emailluka]

nice plugin.

would it be possible to adapt this for another function?
like adding flags of the available languages in the right upper corner of the image?
f.ex. if there are 2-3 languages, add the respective flag in the corner, if more - add a "multi"flag into the corner?

Hey, I apologize for the silence. I'm not active on the forum, and I did just realize that I forgot to reply here for a couple of weeks. That's on me.

I initially shared JellyTag here just to put it out there, without really expecting much traction. The response from Reddit has been genuinely surprising, and I appreciate every comment and piece of feedback.

Quick status update: the project is not abandoned, but development is on pause for now. I'm taking some time to properly learn the codebase before pushing further adjustments. You can read the full context at https://github.com/Atilil/jellyfin-plugins/issues/17.

If you have questions, bug reports, or feature requests, the best place to reach me is directly on the GitHub repo. I'm much more responsive there, and it keeps everything organized

Sorry again for the delayed response!

@JasonThai: As far as I remember, there's a breaking change between 10.10 and 10.11 for the plugin; I don't remember why, though. But there's probably no chance I'll be able to make it, sorry.
@Emailluka: Great idea! The flags are already supported, but you're right that a "multi" fallback when there are too many would make things much cleaner visually. You are welcome to open a feature request on the Git issues so we can track it properly, and I can include it in a future update.
