Alist that specifies how to detect filenames of images to be displayed inline.

The value should be an alist whose elements have the form

      (REGEXP . NUM)

where REGEXP is a regular expression to search buffer text for what might be a specification of an inline image, and NUM is the number of a parenthesized sub-expression of REGEXP which gives the name of the image file to look up.

Examples of image filename patterns to match:
    file://foo.png
    `file://foo.png'
    M-x \[foo.gif (\[foo.gif)]
    <foo.png>
     foo.JPG
