There are a couple of ways around this. The simplest is don't specify
a width or hieght in the html
Otherwise I am presuming your using PerlMagick, you haven't mentioned
what methods/options your using.
You could work out the orientation yourself using the ping method:
($width, $height, $size, $format) = $image->Ping('logo.png');
This gives you everything you need to know quickly.
Good luck.
