(Sketched this down a few months ago but didn't put it into Phabricator; prompted by recent discussions.)

I am thinking about the icons we can use in @Jdforrester-WMF's idea of making the user confirm each of these conditions (checkboxes). Let's refer to this ideas as, Idea A in the future.

I wanted to decide the basic thought behind the icon before drawing it in the MediaWiki Theme style.

[icon] It must be entirely your own creation, not just taken from the Web

Icons of tools of creation like the ones in the Multimedia Projects slides.

It has to contain no work by anyone else, or inspired by them [icon]

• Bulb, as in idea
• Snowflake, to show uniqueness

This one is tricky, especially because the definition of the word inspiration is broad (astronomical animation inspired by a poem??). The contains someone else's work is easier to deal with. Maybe something like: 

[icon] It should be educational and useful for teaching others

• The square academic cap is often the icon for education, but I don't think we are going for that meaning of education.
• Brain inside a head
• Teacher in a class
• Icons of globe, microscope, or lab utensils could convey the meaning too, but become subject specific.

It must be OK to publish forever on the Internet under the Creative Commons license [icon]

Creative commons logo or the icons for CC-BY-SA.

Idea B could be using the same messages as Idea A, but not making the user tick each. It can show up right above the license agreement checkbox.

Idea C Instead of telling the users what right, we tell them what is surely wrong.

Did you get this from an image search?
Did you download this image from a website, including Wikipedia?
Is this a scan or photograph of an existing work?	Icons of tools to scan/photograph

Idea D Before showing the license checkbox, ask some yes/no questions that'll need the users involvement.

• Did you download this image from a website?
• Did you get this from an image search?
• If its a photograph, did you click it yourself?

Users tend to hit 'Yes' without thinking much. Hitting 'Yes' in some of the above cases will not let them upload, and maybe suggest them to use Commons. If they correctly answer all questions, we can finally show the license checkbox.

Idea E Show users suggestions of the right way (idea a) and wrong way (idea c) of doing things. Just an image before the license checkbox.

I think there are few problems here:

1. Users don't understand copyright violation. They read the label for hitting the checkbox, but it doesn't mean much to them. They treat it like the I agree button on any other website that they're used to clicking without reading.
2. Clicking the checkbox isn't a deliberate action, so they don't know what they are doing.
3. Definition of Own work not clear: I googled and downloaded this image on my own, so…

The ideas above try to address these three issues. Not all of them, but each idea tries to address at least one.

Also, the images used above are just representative. I'll be drawing them in the MediaWiki icon, or BetaFeatures image style once we finalize.

This sounds like a good idea. Would be helpful for upload wizard as well.

So user see that it is not allowed to copy files from google etc.

I'd pick A and D for sure. And C or E. E > C.

For Idea E

Image search	Website	Own graphic	Own photo
Cannot upload images found on a search engine	Cannot upload images downloaded from other websites	Can upload graphics you've created	Can upload educational photographs you've clicked

I think the camera one looks bad and no one will understand it.

@Prtksxna

Looks imho excellent!

For Idea A

Thanks! Still working out the last one, "Can upload educational photographs you've clicked", suggestions are welcome.

The complete designs for ideas A, D, E can be seen at T120867#1874985 now.
