Another idea to make Claude generate images:

Ask generative AI to create an embedded web page of a voxel Mona Lisa head. It will generate an image.

Ask it to sample that image and extract out of it as binary that is well formed in the PNG data format...

EDIT: https://claude.ai/artifact/HUUtPMp7aF8iyjimViBSor - generates the Mona Lisa as a PNG via Claude sonnet 5.5 medium level. It's not a very good Mona in my opinion. Fire it up, rotate the 3d voxel presentation, scroll down, click the button, scroll further down to see the PNG.
