I think the word "owner" should be removed as it is very ambiguous. We have many cases of people who think they can upload a photo just because they bought a physical copy.

I also would add a sentence like: "Only use this option if you are sure that you get the permission".

Thanks @GPSLeo for helping improve this workflow. Your suggestion of removing the word “owner” makes sense given people can misinterpret it. I shall update it in the design.

Re adding this copy: "Only use this option if you are sure that you get the permission" - I fear longer the copy gets less likely the users are to read it carefully or fully as always observed in usability tests. Also the option was pretty clear and people did not chose it lightly unless they were told they had permission. So additional copy may not add much but only make the text seem longer, there by taking the focus away from the main message.

[mediawiki/extensions/UploadWizard@master] Add option to cover the usecase of users uploading on behalf of someone else

https://gerrit.wikimedia.org/r/1099723

The patch handles all AC except for the error message, which remains the generic "selection is required" below the entire group.
There already is another ticket about changing how that works (T381286), so let's cover that there - I've added this one to the list in that ticket.

[mediawiki/extensions/UploadWizard@master] Simplify plural in a message

https://gerrit.wikimedia.org/r/1105012

I suggest changing "this media|these media" to "this file/these files". See patch in https://gerrit.wikimedia.org/r/1105012. These are files in any case, and from my experience, quite a lot of people don't understand the word "media" very well, even in English, and even more so in other languages.

Checked in commons beta - all AC are in place:

figma design	commons beta
	the correction of the error placement will be made in T381286

@Amire80 - the change is displayed in commons beta. There are other references to "media" on Special:UploadWizard, any further changes will be needed?

@matthiasmullie - on commons beta the Console error is displayed when "I do not know who the author is" checkbox is checked/unchecked:

Uncaught TypeError: status.getErrors is not a function
    at uw.ValidationMessageElement.postValidate
    at uw.ValidationMessageElement.js:56:32

The error is not present in production. Was it introduced when the new field was added?

Thanks for catching that, Elena. I've submitted a patch that should fix that.
