To remove an image – or another block – from a lesson, there are two ways.
Highlight the block with the mouse pointer and then press “Remove” on your keyboard.
Open the options menu for the selected block and select the “Remove Block” option.

Note: If you accidentally do something you did not intend to do (e.g. remove an image from the lesson), you can use the CTRL+Z key combination to undo the last thing you did.
