A link sent in a messaging app unfolds into a card with an image. If there is no image, the card is grey and the link looks suspect — and a purely textual entry has no photograph by its very nature.
An entry with a photograph gets a light variant of it, around twelve hundred pixels and under two hundred kilobytes. The full frame is often too heavy: some messaging apps simply skip it and fall back to the grey card, even though the image was supplied correctly.
A text entry gets a card built from a single sentence — the one the author marked as the strongest in the text. It is not decoration but a substitute for a photograph: the card has to give a reader a reason to click, and a quotation does that better than a logo repeated under every entry. Entries that mark no such sentence get the site's default image.
