Display Preheader while having a picture header

Content

Greetings

There is a requirement where the customer should see the preheader for each mailing in their outlook account. As of now, they can only see this if there is text written on the very top of the email message (no picture on the top as a header).

Is it possible to keep the picture on the header yet have text to display as a preheader?
