Is there a way to cache all the images displayed in a web page using CodeIgniter ?
If there is , please point me to right direction , a library , anything ...

No I am not aware of any framework that will cache images. That is more a server setting and can be done with .htaccess in some cases:

are the images created dynamically with CI? or do you have them stored in a folder?
in first case you can add headers that tell the browser how long keep the files for.
in second case there are .htaccess stuff that allow you to set these options.
