How to disable auto-image-mode

Question

Whenever I open an SVG file, emacs renders the image in the buffer. I want it to let me edit the text (in nXML mode).

Of course I can exit image mode with C-c C-c, but I'd prefer that my text editor start me off with the text.

M-x auto-image-mode reports that it is toggling the Auto-Image-File mode to disabled, but the file still opens as an image (though smaller, curiously).

Well this seems to drive a stake through its heart:

(auto-image-file-mode 0)
(setq auto-mode-alist (delete '(#1="\\.svgz?\\'" . image-mode) auto-mode-alist))
