Imager is really nice. If you want support for reading/writing JPEG, PNG, GIF and TIFF you'll need to install a couple of extra libraries. Check the README file that comes with Imager to see where you can download them. To support drawing text, you'll also need t1lib and/or freetype(2) unless you're on Win32 where Imager can take advantadge of GDI.

On some platforms, I've found some struggle installing Imager but on linux it usually justs DWIMS. Environment IM_LIBPATH and IM_INCPATH are your friends when installing. And yes, you need to rebuild and reinstall Imager when you add support for these libraries.

If you want to find out what formats your Imager installation supports, there is a %Imager::formats hash that contains the different filetypes and font-lib support
