This extension is a wrapper around VIPS, a free image processing software. VIPS is a set of image manipulation tools specially designed for speed and low memory usage. This is useful for resizing large PNGs.
The extension shells out to the vips binary. It can be configured to scale only certain files (for example: big PNGs) by configuring $wgVipsConditions.
VIPS installation 
Install VIPS. It can be downloaded from http://www.vips.ecs.soton.ac.uk/.
After downloading VipsScaler, add it to your extensions/ directory, then add require_once("$IP/extensions/VipsScaler/VipsScaler.php"); If you'd like to add the Special:VipsTest test page, also add require_once("$IP/extensions/VipsScaler/VipsTest.php");
Debian / Ubuntu 
$ apt-get install libvips-tools
If you want to build from source have a look at upstream documentation: http://www.vips.ecs.soton.ac.uk/index.php?title=Build_on_Ubuntu
Mac OS X
