Lots of users send us screen shots via messenger applications. I work around this in epics and stories by adding screen shots to the mock up but in other tools like V1 I am able to just copy and paste an image directly into the details sections.
In the Ideas Portal there is no create a mock up category. I can tell you that users won't always go the extra mile and create a PDF or an attachable file in order to include those details and thus we lose that information at the door. Kind of counter intuitive to the ideas section.
