While I agree the UK law is nuts, and its citizens either need to revolt or kill all their children & stop breeding (probably for the best) to comply with their law, I'm just writing about principles for robust web content like don't just post an image of text
- the disabled can't read &
- that's vulnerable to failure for any number of reasons including geoblocking due to insane laws.
Text alternatives are resilient to failure & provide richer features (usability, accessibility) than images.
