When no custom images are uploaded for an item, the system displays a predefined global image. If you want to create a custom thumbnail item, you have the option to upload an image in the Items Details tab.
As a best practice, upload your photo in a JPG, JPEG, or PNG format and use an image with an aspect ratio of 16:9 and a file size less than 10 MB. Once uploaded, you can preview the image to see how it will look and decide to keep it or delete it.
AI-assisted capabilities can be leveraged to produce images for content. Upon utilizing the Generate Image feature, a widget will appear, allowing you to enter up to 180 characters to describe the image in a designated text box. After entering the description, you can select Generate to preview the generated image. You have the option to adjust the size and position of the image. If a different image is desired, you can modify the description as necessary and choose to generate a new image.
Note
AI-assisted capabilities require an AI Units license. Additionally, Assisted Image Generation setting must be enabled in AI Services Administration in Admin Center.
