How to enlarge the preview thumbnail in a messageML

By default, the size of the preview thumbnail in Symphony is set to a maximum height of 256 pixels (Figure 1):

Note: The image could be smaller if the original picture is less than 256 pixels.

If a customer wants to make the preview thumbnail larger, use the min-height variable to set a specific size as desired. To do this, you need to specify in the style attribute the min-height for the img element (Figure 2):

<img style="min-height:350px" src=""/>

The new code will then render the larger image (Figure 3):
