I had been using a [% PERL %] block to add scalar_ops and I was hoping
to do the same sort of thing to attach the imgsize function so users
could use it as [% imgsize(imgfile) %] rather than [% imgfile.imgsize %]
which doesn't seem like much of a difference until imgfile is plain
string. I also have a conceptual issue with a vmethod that doesn't apply
to all scalars but that's probably just me.

Thanks for your plugin code. I think that is the way to go.

Many thanks,

Simon.
