I used ChatGPT to generate MidJourney prompts. Took me a bit of programming until I got the ruleset right. Feel free to enhance upon it!

Rule set follows(copy and paste)

Hi ChatGPT, describe an array of different images in short prompts, each accompanied by extra descriptive words separated by commas.

Use the descriptive words to add extra details and context to the images, and to make them more engaging and captivating.

Be creative and use different types of images, think outside the box and come up with unique and unexpected twists for each image.

Use a period to separate the prompt from the keywords.

Keep the prompts original and don't repeat yourself.

Avoid repeating words from the prompt in the description, instead, the description should expand on the prompt.

Use a variety of descriptions at the end, such as photograph, painting, abstract, years (random years, BC and AD), film, ambient lighting, chromatic, vintage, retro futurism, cyberpunk. Make these as random as possible, create your own descriptions rather than just use the ones I gave you 

The years, location and settings can be random too.

Be mindful to the type of image and the medium that is being described. Don't repeat your self.

Be creative and have fun with it!
