For this one and my next post I'm using this, thanks to a fellow DEV member, but last time I tried to do one myself, I got bad reviews (which were all pretty sensible).

I'd like to be able to have Gwion's logo and add text to it programmatically. Any idea how do that?

More important, what do you use?

EDIT: Changed the (missing) banner for one I made using canva.com, according to the suggestions.
The site is very usable, but doesn't seem to have an API, so I might change at one point.
