Resolve ambiguity in photo copyright terms, improper use, and inconsistent permissions

[pmk01]

The copyright options on the photo upload page are unsatisfactory. We need options which cover all scenarios, (including occasions when a candidate wants a photo removed after the election?).

Suggestions by JF & ML in this doc.

Additional option suggestion: I've seen people submit photos from Wikipedia/Wikimedia, which tend to be CC-BY (i.e. attribution) licenses. It would be good to be able to accept these. However, there's no way that I see to provide an attribution, and any attribution would need to be available somewhere on WCIVF & candidates websites.

I saw the submission message for a photo for candidate https://candidates.democracyclub.org.uk/person/119068 had some views on the current options. The message was:

"I do not grant you copyright, but I do grant you licence to use the image for the purpose of displaying the candidate (me) on this website. As a professional photographer, I'm a little perturbed by these terms and conditions - no photographer would hand over the copyright to an image! Feel free to message me if you'd like some assistance in tidying them up."
