Respond_to with MIME type wildcards?

Rails
1

I’d like to respond to requests for all kinds of image MIME types from a
single respond_to. In particular, I don’t want to register MIME types
for each image format, I’d rather define only one with a wildcard, like
this

Mime::Type.register ‘image/*’, :image

Then, in the controller handle it like this

def show
respond_to do |format|
format.image do
# check if concrete MIME type can be provided
…
send_file @image.filename, :disposition => ‘inline’
end

  format.html do
    # send HTML page embedding the image
  end
end

end

As it happens, this doesn’t work. Registered MIME types are matched
literally, the ‘*’ is not interpreted as a wildcard.

The best I’ve come up with is this

Mime::Type.register ‘image/png’, :png
Mime::Type.register ‘image/jpeg’, :jpg, [‘image/jpg’], [:jpeg]

and then

  format.any(:png, :jpg)  do
    send_file @image.filename, :disposition => 'inline'
  end

Is there a another way?
