I don't see any problem with enabling it when using ttree, but it won't 
help since Image::Size doesn't have an OO interface.

Of course since you're already using Perl blocks for your other setup 
work, you could just do this:

[ % PERL %]
  use Image::Size ();
  $stash->set(imgsize => \&Image::Size::html_imgsize);
[% END %]
