Including images dynamically in templates
You can include images dynamically from the business object that you create a mail merge for. This section describes how to add a property image to a property mail merge report as an example.
* 
You can dynamically include images in both HTML- and in DOC/DOCX templates.
The procedure for these templates differ slightly, see:
* 
•    The following file extensions are supported: bmp, jpg, gif, png, jpeg.
•    This is not supported for secure documents.
•    This is possible for flexible subreports, not for simple subreports.
•    The size of the image can be defined by adding a text box and adding the merge code into this text box. Place the Merge code in a table cell within the text box and set the table option AutoFit to Fixed Column Width.
•    The file name of the image used in the mail merge must have a minimum length of 3 characters (or it will not be included).
•    The image can be merged from both fixed fields and expressions, as long as they are targeting an image field type.
