The Gallery feature outputs images according to the position of the file names within the  tags.

You will have to alphabetize the images yourself, or potentially use JavaScript. However, I don't have enough knowledge of the latter to help create a script for you.

You may have more success posting your request on the Forum or Discussions of the Fandom Developers Wiki.
