I don't know what is the file-name extension of that file, so I cannot
give a precise recipe.  Assuming for a moment that its extension is
.png, I see that auto-mode-alist includes this element:

   ("\\.png\\'" . image-mode)

So to remove this, you need to do this:

  (delete '("\\.png\\'" . image-mode) auto-mode-alist)
