Here are the text instructions.
Step 1: Go to your Interact dashboard at dashboard.tryinteract.com and edit a quiz.
Step 2: Click on any image to open the photo editor.
Step 3: The first option is to search for images in the Pixabay.com image library. These are royalty-free as well as Creative Commons CC0. Select any image from the list to get started.
Step 4: Use the crop and resize tool by dragging the selection area, or dragging the handles of the selection box. When cropping, the aspect ratio and size is fixed to the proper dimensions for that particular quiz image. (Note: If you would like to resize below the minimum required image size, you can find the option in the “Advanced Options” section – this is not recommended!)
Step 6: If you have your own images you would like to use, choose “Start Over”, confirm “Yes”, and select the “Upload” tab in order to choose your file.
Step 8: If you have an image which is hosted at an online link – click the URL tab. Then copy and paste the image URL in the box. The only caveat is that you are not able to resize or crop linked images from the internet.
Step 9: If you need to attribute the source to any of your images, you can click the “Edit Attribution” tab. This will create a label on the image which will be displayed in the quiz.
