First of all, the week begins with Sunday. ;-)

And maybe this wasn’t true back then, but you can use ->url_abs() in place of ->url() so you don’t have to manually build the absolute one. So you can replace,

my $item;
 
if(substr($img->url, 0, 4) eq "http")
{
	$item = $img->url;
}
else
{
	$item = $url . $img->url;
}
 

with,

my $item = $img->url_abs;

This will also allow it to properly handle redirects.

Ok, I slapped GPL boilerplate on top of it. Feel free to use it in any GPL compatible ways you wish. :)

Your original source link is broken now, so the HTML version is the only one left. Oh, any chance you could license it to me? :-D Like GPL or BSD or whatever?

Wow, this is exaclty what I was looking for the other day! Some comics include the comic inside the feed. Many don’t, so I can use this to make my improved feed.
