Unlike the free-form landing pages, guided landing pages have predefined, locked spaces where you add images.
Select a guided landing page. Click Edit Draft.
Click the image you want to edit. The element placeholder will illuminate in the landing page canvas.
Select the image you want and click Insert.
The content will display in the element place holder.
How the image resizes is dependent on the template. Learn more about Guided Landing Page Templates.
Specifying a link for an image in the editor is not currently supported. Use a rich text element instead.
