Title: Installing littlutils Last modified: August 20, 2016 --- # Installing littlutils * [gavinhamm](https://wordpress.org/support/users/gavinhamm/) * (@gavinhamm) * [14 years, 8 months ago](https://wordpress.org/support/topic/installing-littlutils/) * I’m getting this message * > CW Image Optimizer requires littleutils. You are missing: opt-png, opt-jpg, > opt-gif. * Obviously because I haven’t installed littleutils, but I’m not sure exactly how to install it, or where to put it. * Is there a tutorial somewhere? Or Can I install it somehow using Cpanel?

Basically you download package and run the following commands in the directory that has the littleutils-1.0.24.tar.bz2 file: 1. tar jxvf littleutils-1.0.24.tar.bz2 2. cd littleutils-1.0.24 3. ./configure 4. make 5. make install 6. make install-extra * Thread Starter [gavinhamm](https://wordpress.org/support/users/gavinhamm/) * (@gavinhamm) * [14 years, 8 months ago](https://wordpress.org/support/topic/installing-littlutils/#post-2215423) * [@zulugrid](https://wordpress.org/support/users/zulugrid/): Thanks.
