Blosxom: How to insert a fixed path for images in Blosxom

I wrote some post on my new site created with Blosxom and I wanted to insert some images that I put in a directory called images under my website address root.
I found different solutions:

I pointed the image link to the absolute web address of the images directory, like this:
<img src = "http://mydomain.org/images/filename.jpg">.
That means if I change domain I would have to change each post I've done (obviously, I would use an automatic tool or script to search and replace multiple files at a time).
A slightly more versatile solution would be to point the image link to something like ../../images/filename.jpg, with one ../ for each level of the category tree I have to go up to reach index.cgi. This means I would point to ../images/ in some posts, to ../../images/ in some other posts, to ../../../images/ in even other posts.
This solution is error-prone and if I decide to move a post into another category that sits on another level I would have to change all the image links in that post.
The solution I adopted is to store the absolute web address of the images directory into a variable in index.cgi and use it in my posts. This is what I did to make it work:
- I added $imagesurl = "http://mydomain.org/images"; right below $url = ""; in index.cgi
- Again in index.cgi, in the first line after configuration settings (use vars qw! $version ...) I added $imagesurl in the variable string
- Always in index.cgi I edited the block where the post file is read:
```
if (-f "$path_file" && $fh->open("< $path_file")) {
    chomp($title = <$fh>);
    chomp($body = join '', <$fh>);
    $fh->close;
    $body =~ s/\$imagesurl/$imagesurl/g;
    $raw = "$title\n$body";
}
```
  The line I added is the $body =~ s/\$ imagesurl/$imagesurl/g;, telling the cgi to substitute in the body read from the file the string $imagesurl with the content of imagesurl variable.
- Finally, I changed my image links to <img src = "$imagesurl/filename.jpg">.
After all this, all my images are displayed correctly, and if I change my domain I only have to change the value of my variable; and when I move a post I have to do nothing.
