Hi Marketo Nation,
I am using the following endpoint to update an image within the email content: https://developers.marketo.com/rest-api/endpoint-reference/asset-endpoint-reference/#!/Emails/update...
I have not found a way to leave width and/or height for the image empty. This would meet the spec in the email template, where the image placeholder is set with `width` being "600", and `height` is not provided/fixed. For now, the image always appears distorted. (Note that upon manual image upload/specification from within the email builder it works as expected.)
How do I need to alter the POST request to get an empty `height` attribute for the image? I have fiddled around with "null", but to no avail.
