The image isn't loading for me, all I see is the prompt used to generate it - which is genuinely preferable.

For me it was showing the image and the prompt, but the whole page was unstyled. But when I reloaded the page now, the css loaded also and the prompt is not shown.

I guess the web server was temporarily overwhelmed by traffic resulting in images (like for you) and css files (like for me) not being consistently served to all visitors.
