Every image needs to be at most 3000 pixels wide & 3000 pixels high. For constraints on minimum dimensions - see below.

Header image 

  • This is the image that will be displayed at the top of your full story, also the image that will be added in your email campaign. Read more
  • It needs to be at least 1108 pixels wide. No constraint on minimum height (but it's recommended not to use an image that is too tall that will make the text of the story go below the fold, i.e. people will have to scroll before they can see the text, which can be easily missed).

Main image 

  • This is the image that will identify the story inside your newsroom and on socials when you share it. Read more
  • It needs to be at least 1024 pixels wide. No constraint on minimum height. 

Images inside a story 

  • No constraints on minimum dimensions
  • For GIFs, we recommend no more than 6 seconds and a max. of 8 MB to ensure it displays well for your recipients and doesn't eat up too much data if they are viewing your story using a mobile device.
