Any CPAN module for creating thumbnails?

[B. Fongo]

I wander if here a way to create thumbnails using Perl?
 
I want to implement functionality for my shop program to create a
thumbnail of product pictures.
A good instance of it may be that of eBay. Users can upload a picture of
any dimension for their listing. EBay will automatically create a
thumbnail of that picture for the gallery.
 
 
Thanks
