Description.

An updated version of https://greasyfork.org.cn/en/scripts/482793-always-hi-res-c-ai-avatars/code. It:

• Loads profile pictures in their highest-available resolution (400×400px).
• Loads profile pictures in their highest-available quality (100%).
• Removes the limitation on animated profile pictures, allowing them to be animated again.
• Unless chosen otherwise, also manually fetches original sources for the profile pictures (see more below).

Notes.

[1] Image loading.

Sometimes, the images will not load the full-resolutions ones right away. For example, when searching, the first few results will have the 80px profile pictures. Scrolling down a bit and going back up will update them properly. Furthermore, some images on Character.AI do not have a 400px variant, for some strange reason, and can appear as just plain text. Whilst these are few, they do exist.

[2] Reporting of characters on Character.AI.

Sometimes, manually-replaced images uncrop the ones uploaded on Character.AI, leading to seeing of potentially not safe content. If such is the case, please feel free to report the Characters and Character Creators on Charcater.AI itself at https://support.character.ai/requests/new. I cannot be Character.AI's moderation, and my own reports do not seem to help. See below for a version containing only higher-resolution images from Character.AI and not external sources.

[3] Simpler script not pulling images from external sources.

This script also manually fetches original profile pictures of characters I have come across in my recommendations. This part is network-intensive, and most likely not desired by a lot of users for the reason above. If you only want to load the profile pictures in their highest resolution and quality from Character.AI, you can simply remove that part, so, basically, using only this:
