100 image styles: A prompt builder

Punya Mishra built 100 Image Styles, a web tool at punyamishra.com/imagemaker/ that generates AI image prompts from 100 design styles, adapting John Hartnup's Poster Prompts list. Users select what they are making, describe a subject, and choose a style — spanning Art Nouveau, Bauhaus, Risograph, Madhubani, 90s rave flyers and early PlayStation low-poly — and the page writes a prompt to paste into ChatGPT or another image tool. The tool also lets users request clear space in the image so real type can be added afterward, since AI tools draw letters rather than set type.

Kottke.org https://Kottke.org is one of those sites I have been following for a while now, and a while back Jason Kottke linked to John Hartnup’s Poster Prompts https://john.hartnup.uk/poster-prompts . John wanted to see what range of visual styles AI could produce beyond the typical AI slop , and ended up creating prompts for a hundred different design styles for AI image generation. These ranged from Art Nouveau and Bauhaus to Risograph, Madhubani, 90s rave flyers and the low-poly look of early PlayStation games. Each style spells out its visual traits, lettering, palette, layout and mood, and a list of things to avoid. I make a lot of images for this blog and for Silver Lining for Learning https://silverliningforlearning.org/ , and I have hated and fought this default AI look as well, in my own way. So seeing John’s list was exciting and I could not resist adding to my image generation toolkit. Moreover, John focused on creating posters, but my needs were a bit wider, including feature images for blog posts, the occasional slide, a banner or a book cover. So I built my own version on top of his. You pick what you are making, describe your subject, and choose one of the hundred styles, and the page writes a prompt you can paste into ChatGPT or any other image tool. Since AI tools draw letters rather than setting type something John wrote about here https://john.hartnup.uk/2026/09/23/poster-svg.html , you can also ask it to leave a clear space so you can add real type yourself afterward. I shared this with John and he was kind enough to say I could use the prompts however I wished. I can see myself using this a lot, and I hope others find it useful too. In fact, the featured image at the top of this post was created using one of the prompts created by this tool. Here it is: 100 Image Styles https://punyamishra.com/imagemaker/ , enjoy.
