The error message is simple the message that I have written after .... or die "No Image Captured".

Read my posting again. I told you where perl hides more information, and that you should write that information somewhere when an error occurs.

Compare to the usual idiom for opening files:

open my $f,'<',$filename or die "Can't open $filename: $!";

Also note that $! will most likely not help you, see my first posting.
