Replacing image
[edit]It is so much simpler to merely go down the page to the "File history", click on "Upload a new version of this file", and upload the transparent image. There is then no need for: "After doing so, please replace all instances of this version..." since, as soon as the edit is done, all instances have already been replaced.
