💡 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
Customization
For images in Page cards, you can zoom in and out, move the image around within its container, and add background if image is zoomed out from its container.
Through the menu, you can:
Change the image format
Zoom in/out
Add alternative text, image credit and hotspots

💡 Pro tip! Use these features after adding the picture to a column - and see what amazing designs you can create.
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.
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 'Create hotspot' option (represented in the three dots dropdown).

Avatars allow you to create engaging video content directly in your course without the need for pre-recorded videos. They can deliver either your written scripts or AI-generated scripts based on course content, offering a flexible and efficient way to enhance learning materials. Avatars make content more interactive and visually dynamic, providing context and simplifying complex topics. They introduce a human-like presence that makes courses more relatable and engaging.
💡 This is available in both live and self-paced learning scenarios, making it suitable for various training needs.
