Images of text break much that text alternatives do not. Losses due to image of text lacking alternative:

• usability
  • we can’t quote the text without pointless bullshit like retyping it or OCR
  • text search is unavailable
  • the system can’t
    • reflow text to varied screen sizes
    • vary presentation (size, contrast)
    • vary modality (audio, braille)
• accessibility
  • lacks semantic structure (tags for titles, heading levels, sections, paragraphs, lists, emphasis, code, links, accessibility features, etc)
  • some users can’t read this due to lack of alt text
  • users can’t adapt the text for dyslexia or vision impairments
  • systems can’t read the text to them or send it to braille devices
• searchability: the “text” isn’t indexable by search engine in a meaningful way
• fault tolerance: no text fallback if
  • image breaks
  • image host is geoblocked due to insane regulations.

Contrary to age & humble appearance, text is an advanced technology that provides all these capabilities absent from images.
