After the user presses the "Publish" button from the captions step in T290781, they advance to the edit summary screen.
Note: Final copy updated below - see relevant tab for corresponding QQQ in the copy spreadsheet

• Overall
  • This is a similar experience to the same step in "add a link" (T269657).
  • It does not contain any free text field for an edit summary, or checkboxes for "watch this page" or "minor edit".
  • Just as it usually does, the header should contain a back arrow to close it on mobile. This leads back to the "captions" step, where the user's caption should still be in place in the caption box.
  • Just as it usually does, the header should say, Save your changes.
• If the user accepted the image
  • The publish button should say, Publish just like it usually does.
  • Body
    • Header: Summary (same as add links)
    • Below the header is a gray line.
    • Next, on the left side should be the bolded filename with a small image icon. On the right of that row should be a checkmark.
    • Below that should be the image preview.
    • Below that should be the caption.
    • Last is where we put the publishing disclaimer which is unique to each wiki: By publishing changes, you agree to the...
  • The footer should have the standard Review your changes button. This should open up the visual diff review, just like it usually does.
  • After tapping the publish button, the changes should be published to the wiki according to the rules in T290785: Add an image: edit business rules.
  • The published edit summary should use the same logic as implemented on T284078: Add a link: change the edit summary, and be like, "Image suggestions feature: 1 image added." It should include the edit tag described in T293166: Add an image: edit tag.
  • The page should be automatically added to the user's watchlist (note that the mockups below include the feature described in T289547: Structured tasks: give users options for watchlist, which is not required for Iteration 1).
• If the user rejected the image
  • The publish button should say, Submit.
  • Body
    • Header: Summary
    • Below the header is a gray line.
    • Next, on the left side should be the bolded filename with a small image icon. On the right of that row should be an "X". Note: there should be no "X", even though there is a checkmark for the accepted image. Filed here: T295795: Add an image: remove "X" from edit summary.
    • Below that (same as the caption text for an accepted image) should be the text: This image suggestion was rejected.
    • Last is where we put the publishing disclaimer which is unique to each wiki: "By publishing changes, you agree to the..."
  • The footer should not have a "Review your changes" button.
  • After tapping the submit button, nothing should be published to the wiki, and there should be no edit summary.
  • The page should not be automatically added to the user's watchlist.
• No matter what the user has and has not chosen, a log entry gets created per T293169: Add an image: log entries.
