[Templates] PATCH Image plugin fails with Image::Size

[Axel Gerstmair]

Hi all,

while testing the current developer release of TT, version 2.09a, I
stumbled upon an error with the Image plugin. The error occurs only if
you are using Image::Size and don't have Image::Info installed. Below
is a patch that fixes the problem.

Best regards,
Axel
