I would like to test if *.ico images are valid icons in PHP. I tried to use getimagesize function but it doesn't support ICO files.

ico files are mainly image files, if you change a jpeg or gif/png into ico extension it works fine,so if you keep image type cheking it will do the job

or you can check the mime type which is "image/x-icon"

this is not what I want, I need to check them because I downloaded some from net with CURL and they're sometimes 404 pages

icon must start with the '0x00 0x00 0x01 0x00' bytes, it shall be enough for simple test.
