Imagick provides various ways to identify image properties. These properties include for example some basic attributes like width, height, format and some more advanced attributes like exif tags, profiles and colorspaces.
Test image test_imagine.jpg
The output looks something like this:
Basic image properties:
Image geometry: 1024x768
Image format: JPEG (Joint Photographic Experts Group JFIF format)
Image type: TrueColor
Image compression: JPEG
Image size: 129.955kb
