Well, once the first line fails, there aren't any images for it to work
with, which explains the other error msgs. It is telling you that that
Image::Magick, as you've got it installed, can't handle .PNG files. Which
may mean it's installed wrong, the png library is installed wrong or just
that the one can't find the other. You might try tests with other formats
to see if any format is usable, which might help debug the problem. You
might try re-installing Image::Magick, esp. if you installed it before you
installed libpng
