User feedback from user testing "what is this icon supposed to mean", "shouldn't this be a picture of a document or a video or image?":

As a SecureDrop source, I want icons to aid in my comprehension of the functions of the interface.

More thoughts on the pancake icon: DropBox and Google Drive's web interfaces at least use either no icon and just a text button or a blank file with an arrow like this: https://thenounproject.com/term/upload/1268576/.
Looks like there's already an upload icon being used in-line with the submit button; Arrow in a cloud. It's a bit out of place in the button imho; It might be advisable to replace the pancake icon with the cloud icon, then use a single-color checkmark-in-a-circle icon for the Submit button and add a x-in-a-circle for the Cancel button.
Thanks for the feedback - I like those suggestions @huertanix
I can update the icons based on @huertanix's suggestions and submit a PR.
Hi Hi: The design rationale that had the "pancake icon" put in the Source UI in the first place, was that the prior icon used the cloud semiotics鈥攚hich is misleading, because SD is not a cloud service.
It is hypothesized that this will matter a lot to sources keen on security things (and who likely are going on anecdotal "I learned this from Oprah" knowledge of info/opsec). Hence, I came up with the pancake icon... which later user feedback flagged as confusing. I would strongly recommend (per the OG rationale that had the pancake icon added) changing the icon to something that addresses the first issue鈥攂ut is more clear. The icon used in these mockups is more widely used today, than the pancake icon ever was鈥攁nd is what I've been working with in the Source UI.
Will create separate issue to recommend the swap-out, and will add to near-term UX meeting agenda.
