While many image viewers can show much of the EXIF data of an image, the one of my choice – fast and light GPicView can’t. Searching for an alternative, I found useful services which need you to upload your images. However, exiftool is already available in the repos and does the job well. As I found from synaptic, it is installed as part of the package libimage-exiftool-perl. It’s worth noting here that you can use the libimage-exiftool-perl utility to write exif data to images as well. exiftool shows all the EXIF information of an image in the terminal.
To install on Ubuntu, run:
$ sudo apt-get install libimage-exiftool-perl
Usage is very easy. A sample run on an image:
$ exiftool Android_logo.png

Somehow you seem to have pasted the ExifTool output twice into your post.
Hey thanks a ton! Will change it shortly 🙂
