Social visual alt text от Nick DeNardis

This extension is designed for individuals who are interested in viewing the alt text applied to images without the need to inspect each image or use a screen reader.

It makes the alt text on social media posts visible to sighted users on Twitter, Instagram and Facebook. Human generated alt-text is visible on a blue background, AI-generated alt-text has a maroon background and images without alt text have a red line under the image.

Each site and colors can be changed in the extension options to meet your needs.
