Hi johnrheyj,

That 'word/media' is not appian path it is word template path. If you have 7 zip in your system then right click on your document template and extract it. Then you can see the path of the image you kept in your word document.
For example: In previous comment i added one document right. Just extract it with 7 zip and you can see the path and images in that path.
And coming to the smart service you just need to pass the document so that in will exract the file update the image in that zip file and again convert it into document and return it as output.

About the issue of corrupting: I didn't faced any issue like that till now. May be the problem is with your template. So please check and update it once.
