Get useful image information on the command line
ImageMagick is an incredible set of programs that allow you to get all sorts of information on image files from the command line, as well as batch edit and generally alter images of many varieties. You can read all about these facilities on ImageMagick’s well-made documentation site.

1 | alias imginfo="identify -format '-- %f -- \nType: %m\nSize: %b bytes\nResolution: %wpx x %hpx\nColors: %k'" |
This produces a succinctly helpful output:
Often this is all I need for basic tasks. And if more is needed there’s always the full ImageMagick suite.
You can alter the format to whatever you prefer, using the wide variety of variables.
