- Only use single upload fields. No multi-file upload fields.
- You must limit extensions to jpg, jpeg, png, gif.
Add dynamic images using the Image block
- Add an Image block to your template.
- While it is selected, open the Block editor sidebar and change the Mode to Dynamic.
- Select a merge tag in the Merge Tag drop down.
- If you want to add a specific merge tag from a form that isn’t mapped to an Email Customizer global merge tag, select Add a Custom Tag and add your merge tag to the Custom Merge Tag field.
- Select the Add Default Image checkbox to add a default image for instances where an image is not added by the merge tag.
- When this is selected, use the normal image upload/replace functionality to set an image for the Image block.
