Every post needs a picture. Stop paying a stock library for the wrong one.
Describe what the post is about and get original artwork for it, in your own brand colours, sized for the article header or the feed. Nobody else has the same image, and it lands in your library rather than your downloads folder.
A sentence beats a word. Say what is in the scene, not what the article is filed under — “a hardware shop owner unloading stock in the rain” gives it something to draw; “retail” does not.
Why the pictures avoid writing
No image model can spell. Ask one for a shop and it will draw a sign, and the sign will say something that is not a word — so these are composed to keep lettering out of the picture rather than asked politely to leave it out. Small background signage can still come back with a squiggle on it; anything you need to be readable belongs on top in Studio, where it is real text you can edit.
What “on brand” actually does
It reads the accent and highlight colours from your brand kit and asks for those, by name. It does not paste your logo into the picture — a logo redrawn by a model is not your logo, and it is the one part of a brand that has to be exact.
