Step 1: Upload images
In the admin menu: Website, then Media Library
Drop images on the upload area, or click it to choose several at once. JPEG, PNG, WebP and GIF files up to 10MB each work. They upload straight away; there is nothing to save.
An uploaded image is not on your site until you put it on a page.
Step 2: Put an image on a page
In the admin menu: Website, then Site Editor
In the editor, click a section with a picture, click "Media Library" on its picture field and choose the image. Then publish the page.
