All Punchh apps running up to date framework will automatically resize Hero Images to 900 x 700 pixels. This is in order to leave some room for padding in the rich messaging Hero Image template of 1200 x 800.
If running a less recent version of the mobile app framework there are options:
- You will need to resize images to 900 x 700 pixels before uploading the image in the Configure Rich Message setup section of a campaign. For instructions on adding a rich message to a campaign (Click Here).
- There is a workaround for apps running older framework using a hero image resizer code in the CSS for rich messages template in the Punchh Platform. For instruction on adjusting the image size using CSS (Click Here).
Note: Punchh built mobile apps that do not automatically resize images to 900 x700 are not running up to date Punchh mobile app framework.
