Configure DOCX from dynamic template - images

Hello,

i am using this smart service from plugin "Advanced document templating" to fill a word template with process data. Everything is working fine for text fields, but i do not know how can i insert image from appian into the docx.

In attached picture you can see node inputs for the smart service. There is node input for Images but i have no idea how and to which field in docx template it should be mapped.

For text fields i have prepared docx template with MergeFields doc.project.name and doc.project.surname. Into XML data model i put:

="<project>"&"<name>"&pv!name&"</name>"&"<surname>"&pv!surname&"</surname>"&"</project>

When i run this process, new document is created and correctly filled. But i do not know what should i put into Images node input Value and which field has to be created in docx template.

Thanks
