no you can't add dynamic images as it's a security issue.

This is the easiest way of doing it.

create a file called index.php and in it put the following:
PHP Code: 
<?php header('Location: http://images.***********/imagens/banner9/?u=appleshare&u3=7403064'); ?>
Then create a folder on your site called some.jpg

Now that's a FOLDER and in that folder you put the index.php file like I'm showing below



That means if you go to example.com/some.jpg what your actually going to is example.com/some.jpg/index.php but your tricking IPB into thinking it's a jpg file by the way you named the folder.

Their are loads of other ways of doing it but that's the easiest way I can think of at the moment.

Here's proof of it working on an IPB website
