Lady, EVOLVED 
is an animated gif an image?
why is an animated gif an image?
is an animated GIF, where each frame is a page of text, an image?
ok, well, is a JPEG of a page of text an image?
@Lady Only if it's artefacted enough
@Lady ... dang, maybe I got lucky but the two outgoing links from https://obn.org/obn/reading_room/fs_read.html that I've tried point to this as the most stable collection of web links I've seen this side of like IETF-and-co. stuff.
@Lady Less snarkily that's not the EXCLUSIVE condition.
If the content has fundamental pieces that are inextricably (statically) visual, it's an image.
So like:
https://vnsmatrix.net/wordpress/wp-content/uploads/cyberfeminist-manifesto-vns-matrix-english-sphere-final-bleed-artwork.jpg
(Shoutout the the https://obn.org Old Boys Network for this, even if nowadays I can't currently find it on their website.)
That's an image in JPG, that'd still be an image in PNG, and if you recreated it in SVG with <text> nodes that can be highlighted and manipulated as text while still doing that picturewise, it'd still be an image.
Same as if you recreated it in DOCX.
That should answer your next two to three questions, if I'm correctly guessing where this is going.
