Seems to give a 'Read error' warning if the size of the file is very small (2 bytes). I think this is because it needs a min 3 bytes to determine the file type

libexif can also be used to parse image info out of id3 tags: exif_read_data("mp3_with_2.4ID3TAGS, '', true, false);

After looking for hours, I found a very good source for exif related programs here: http://drewnoakes.com/code/exif/index.html It lists exif specifications (pdf), a few good links to exif related stuff. The best source I have found in my quest to understand exif better for use in php based exif tools.
