I'm describing the downsides of publishing text on the web as a image file, instead of real text. For example:
- Images are inaccessible for users with visual disabilities (screen-readers need something to speak)
- Images are harder for services (like Google) to index and search for
- Images are near-impossible to process and extend with browser extensions and functionality (Ctrl+F, user-chosen fonts, etc.)
I have terms for each of these use-cases: "inaccessible," "machine-unreadable," and "inextensible." But I need to consolidate them into a single term (classification restraints).
I've considered "opaque," but describing images as opaque would more suggest lack of transparent pixels.
