The AI never adds images. It has no way of knowing your logo, your face or your product, so anything it named would be a made up picture. Images are yours to add.
Where to add them:
- A hero image: open Edit Content, find the hero, set Layout to one of the Split layouts and paste your image address into Image.
- Your headshot: the About section's Image field.
- A video poster: the Video section's Poster field.
- Anywhere at all: Edit HTML, and add your own img tag.
Rewrite Page and Regenerate Section always keep the images you added. A hero with no image uses the centred layout, so a page never shows an empty picture box.
A funnel built before version 1.3.7 with a large picture you did not choose:
Open Edit Content, find the hero, clear its Image field and set Layout to Centered.
