We weren't attaching the image through a GroovyScript, we were populating a variable with encoded data via Groovy Script and trying to pass that in to the XML structure of the request.
We had originally configured the request by pointing it to a file on the file system however we "deleted" that part of the request by clicking the delete button within the Form. There seems to be a bug with that as the request is still adding the photo to the request anyway.
With regards to submitting the project file to Eviware, I'll have to ask about the NDA process.
