Get dimensions of images

Are you implementing a design to HTML, and need a quick reference of the dimensions of asset images? Try:

$ identify *.png

This gets you:

bg-footer.png[1] PNG 30x30 30x30+0+0 8-bit ...
bg-linen.png[2] PNG 128x128 128x128+0+0 8-bit ...
email-facebook.png[3] PNG 32x32 32x32+0+0 8-bit ...
email-signature.png[4] PNG 202x23 202x23+0+0 8-bit ...
email-twitter.png[5] PNG 32x32 32x32+0+0 8-bit ...

Be sure to install ImageMagick first.

$ sudo apt-get install imagemagick  # Ubuntu
$ brew install imagemagick   # OSX
