Download the "Imager" distribution from cpan, run the Makefile.PL and
check its output.
It'll list whether or not it's found the libraries for each file type.
I suspect either they're not installed, or it's not finding them.

On fedora, it's just a matter of:
    yum install giflib-devel libpjeg-devel libpng-devel libtiff-devel
(plus any other libraries you want)
And then rebuilding and installing Imager.pm
