PRESTO platform allows you to engage with customers through rich notifications using images. For a successful image push notification campaign we recommend you to use an image which adheres to the following specifications.


  1. Image Dimensions - 640px(width) x 320px(height)  (2:1 aspect ratio)
  2. Image size should be less than 1 MB
  3. The core content area inside the image should fit in a rectangular area at the centre of the image with the following specifications :
    • Aspect ratio of 1.79:1. Recommended size is 572x320 (pixels). (width x height)
    • This means the image which is 640px wide, will have a margin on 34px on the left side and 34px on the right side
    • So the core visible content will be centred and will occupy a width of 572px
    • Content height will be 320px itself, no margins needed at the top and bottom


In case image notifications are not enabled in your notification console, please contact your Presto representative to get it enabled.
