type is the output of "file" utility:

$ file -b 2_34ub2.png 
PNG image data, 540 x 403, 8-bit/color RGB, non-interlaced
$ file -b 1_e945d.jpg 
JPEG image data, Exif standard: [TIFF image data, little-endian, direntries=6, xresolution=86, yresolution=94, resolutionunit=2, software=Adobe Photoshop Lightroom 5.0 (Windows), datetime=2014:03:27 21:16:12], baseline, precision 8, 1000x658, components 3

Of course, you can create a regular expression that matches all such lines, but it will be
too complicated.
