First, enable the Photo Calendar option in the calendar widget settings.
Next, upload an image or gif you'd like to use, to your 'My Files' section in Mango Display.
Then select the uploaded image, and click on the 'Copy Image URL' button. This will copy a unique Image URL (beginning with https://myimages.mangodisplay.com/) to your clipboard.
Go to your calendar event that you want to display an image for and paste this copied Image URL into the location field. If you already have a location entered simply add a space and paste it after that.
Follow a similar process for any other events that you want to display images for going forward.
That's it! Works with all calendar sources. Images will automatically be displayed on your Mango Display.
