How to test if a module is installed ?

[Dennis Senftleben]

Hi !
My perlscript uses the Image::Size module.
It works fine if it is installed, but if not I get a compilation error msg.
How can I test with perl if it is installed on my system ?
Is there something like 
if ( -e Image::Size ) { use Image::Size ;}
        else { print(" module not installed");}
