In addition to the the ‘Public Image Library’ and ‘My Image Library’, you can use the AI Image tool to add AI images into your mailers.
Just click on the Image tool and select ‘AI Image’. Type a prompt into the prompt image box to describe what you want for your image. You can be as detailed or general as you like. Click the ‘Generate’ button in the modal and the AI will generate image options for you to choose from. Add the preferred one to your page by selecting it and clicking the ‘Use’ button. Note that the AI can make mistakes when it does words as part of the image (for example, if you prompt it to add “Happy Holidays”), so check those carefully. You can always add your own words via a text box.
