Get Image Dimensions from Command Line
The command line is a gold mine if you come from the perspective of a UI lover. Getting information from the shell instead of opening an app, finding a file or directory, etc...what a novel concept. Opening different image files opens up different apps on my Mac and, as the kids say, "ffs" -- I just want to know the image dimensions.
Using ImageMagick you can find the dimensions of an image from command line:
# Get the size of a JPG
convert photo.jpg -print "Size: %wx%h\n" /dev/null
# Size: 600x872
# Get the size of a PSD
convert website-design.psd -print "Size: %wx%h\n" /dev/null
# Size: 990x1200
You can get the image dimensions of any image type from PNG to JPG to GIF to even PSDs. And the resulting text is as plain as it could be. Dimensions...here you are.

![Detect DOM Node Insertions with JavaScript and CSS Animations]()
I work with an awesome cast of developers at Mozilla, and one of them in Daniel Buchner. Daniel's shared with me an awesome strategy for detecting when nodes have been injected into a parent node without using the deprecated DOM Events API.
I like to use ImageMagick’s identify command. Easy to remember and gives the size along with some other helpful info:
but that means having ImageMagick installed.
on a mac you have the native
sipscommand that returns info and modifies image files.ex. to get all sorts of info on an image just do:

Wow, thanks for the heads up! I didn’t know about
sips!Wow! I always wonder why the command
fileis so unknown on the Mac?No need to install anything! Use
man filefor more information. Works for every kind of files, not just images:
