You have the option to add 1 image to each question. You will find the Upload Image button just below space where you type in the question text (see the screenshot below).
There are 2 ways in which you can upload an image:
1. By selecting the file from your desktop and uploading it.
2. By pasting in the URL of the image. (This is useful if you want to add images you found on the web.)
How to get the image URL from a website? Most of the time, if you right click an image, it will give you an option to "Open image in a new tab". Click this, and it should open a new tab with the URL of the image in the address bar of the browser. Copy this and paste it into Quizizz.
