One thing I love about the free version of ChatGPT is that if you've maxed out your uses on creating images, it will actually complete it within the 24 hours and be waiting for you when you return. At least, when I edited one of the images, it was there the next day, as well as generating the caricature that was on trend this year.
Yep, it just needs to that timeout over with, so it's not too strict about it, thankfully :)
I have premium version and I do not get waiting time.
