I tend to stick to regexps for simple things like this and only move to the CPAN modules when processing of nested tags is required. Image tags in HTML are complete and cannot contain any other tags within. So, a regexp solution:

  my $class = "large-image-right-landscape";
  $content =~ s{
    (        # start capture
      <img\s # opening of img tag
      [^>]*  # everything to the tag end
      >      # tag end
    )        # end capture
  }{
    <span class="$class">$1</span>
  }sigx;

The /sigx means not to treat newlines specially, ignore case, perform the replacement globally on the string, and use the layout given above with comments interspersed.
