If I understand correctly, you need smaller image files?

Is it possible to use the default link paths that are already provided by Themoviedb in converted form?

The /configuration endpoint can list all available sizes.

https://image.tmdb.org/t/p/{selected_size}/{backdrop/poster path}

@youssefrabei said:
I want to use the discover path but i need the backdrop_path and poster_path to be with a "specific aspect ratio (lower)"
I'm using the API on my latest website and i use the posters with a small width and height but with the BIGGEST aspect ratio so it's loading 16-20 seconds Per Row slower because of this
So if anyone can help ASAP

See here: https://developers.themoviedb.org/3/configuration/get-api-configuration
Some older ones may still work. But they can die at any time.

"specific aspect ratio (lower)"

The Aspect Ratio cannot be specified or modified in the URL for the TMDb Server.
Only the size in pixels.

These are official sizes:

images  
base_url    "http://image.tmdb.org/t/p/"
secure_base_url "https://image.tmdb.org/t/p/"
backdrop_sizes  
0   "w300"
1   "w780"
2   "w1280"
3   "original"
logo_sizes  
0   "w45"
1   "w92"
2   "w154"
3   "w185"
4   "w300"
5   "w500"
6   "original"
