Page and other cards that support image block recommendation:
As image blocks on page cards can have varying sizes the below is only recommended if you’re wanting to upload a full-width image.
Want to adjust the cropping of an image? In the Title card, Image card, and Image + Text card, you can fine-tune the cropping settings by selecting either "Cover" or "Contain". Choosing "Cover" will zoom in on the picture to fill the card's frame, while "Contain" will display the entire picture within the frame.

💡 Due to variable screen sizes and aspect ratios, image sizes will vary for different users. It is recommended that important information on an image is centered with a suitable trim line. This is not necessary if uploading images on a page card
Image Hotspots
Consider using image hotspots to transform static images into interactive learning tools. Image hotspots are effective for drawing learners' attention to specific content, whether it's explaining complex diagrams or highlighting key details.
How to create an image Hotspot in the course editor:
Add the 'Page' card.
Upload the image that you want to add a hotspot to.
Click on the uploaded image. A toolbar with several image editing options will appear above the image.
Select the 'Click to create hotspot' option (represented by an eye icon).
