AI-generated images create a specific performance problem most optimization guides don't cover: you don't know the image dimensions, format, or content until generation completes — but you still need to avoid layout shift and slow loading.
Here's how I approached it building free AI image generator no sign up unlimited.
The Core Problem
Standard image optimization assumes you know the image ahead of time — you can pre-calculate dimensions, generate responsive srcsets, and optimize at build time.
Generated images break this assumption. The image doesn't exist until the user requests it. You can't pre-optimize what doesn't exist yet.
