I think your previous patch was better. `image-type-auto-detected-p'
should be a simple function whose sole purpose is to auto-detect the image
from the file content.  For users who don't care about negligibly small risks
of viewing any image, it would be easy to override the default element
`(image-type-auto-detected-p . image-mode-maybe)' in magic-mode-alist with
`(image-type-auto-detected-p . image-mode), thus always displaying images
auto-detected as images from the file content regardless of the file
extension (here I mean `image-type-auto-detected-p' is an original
implementation, not from your latest patch).

It is the function `image-mode-maybe' that should decide (ask the user
or use some option) whether display the file as an image, or put it
in `image-minor-mode', or something else (even the word `maybe' in
`image-mode-maybe' indicates the uncertainty about the outcome of this
function).
