How to install Trimage (http://trimage.org/) image optimizer on Linux?
I did it this way:


wget https://github.com/Kilian/Trimage/archive/master.zip
unzip master.zip
cd Trimage-master
python setup.py install

or mirror:


wget http://internetlifeforum.com/files/Trimage.zip
unzip Trimage.zip
cd Trimage-master
python setup.py install

or debian:


apt-get install trimage

then i see Trimage installed:


man trimage

So to optimize image, one do command:

trimage -f filename.jpg
trimage -f filename.gif

To optimize images recursivelly:

find /home -type f -name "*.jpg" -o -name "*.png" -exec trimage -f {} \;
(i would backup before running that on /home)

This eror can happen on Trimage run:

Traceback (most recent call last): File "/usr/lib/python2.6/site-packages/trimage/trimage.py", line 14, in <module> from PyQt4.QtCore import *ImportError: No module named PyQt4.QtCore
It is mentioned to do: apt-get install python-qt4
But on CentOS, python-qt4 is not there. There is "yum install PyQt4", but it request to install 40Mb of SW.. :/
