Two situations favor text slides.
The topic has no visual. A price change, three tips, how an appointment booking works, a frequently asked question and its answer – there's no photo that carries content like that. A stock image would just be filler.
There's simply no good photo right now. Not every week produces a usable image from the business. Text slides fill these gaps without looking arbitrary.
What text slides are not: a replacement for real photos from your business. Photos of the team, the shop, and the work remain the strongest material, because they belong only to you. Text slides are the complement for everything that's better told than shown.
