Customize your Lessonly tenant by adding images. This article contains a list of the images you can upload and the recommended dimensions for each type.

Images wider than 750px will be resized to that width. Image height is not adjusted. You can prevent your images from being squashed and stretched by resizing them before adding them to Lessonly. This in-browser resizing tool is free and easy to use.

For more information on images and adding them to lessons, check out this lesson on design principles.
