I just launched 24picture — an all-in-one AI image studio with 9 specialized tools. Built with PHP 8.4, MySQL 8.4, and Nginx.

In this post I'll share the architecture decisions, the nastiest bug I encountered, and what I learned shipping a real AI product.

What I Built

Instead of yet another "text to image" wrapper, I built a platform with 9 tools:

Text to Image — 3 AI models, up to 4K resolution

Image to Image — transform existing photos

AI Upscale — enhance images up to 4K

AI Model — virtual model photography

AI Tattoo Design — custom flash sheets in 7 tattoo styles

AI Sticker Maker — die-cut stickers from text prompts

Photo to Anime — turn photos into anime art

AI Photo Notes — stylized photo annotations

AI Polish — one-click prompt enhancement via DeepSeek API

All tools share the same backend — one create.php to submit jobs, one status.php to poll results.…
