This module implements Highslide JS, an open source image, media and gallery viewer written in JavaScript. These are some of it's advantages (taken from highslide.com):
Quick and elegant looking.
No plugins like Flash or Java required.
Popup blockers are no problem. The content opens within the active browser window.
Single click. After opening the image or HTML popup, the user can scroll further down or leave the page without closing it.
Lots of configuration options and scalability without compromizing on simplicity. A component system lets you strip away unused features down to a filesize of 10kB.
Outstanding, unconditional and free user support for both commercial and non-commercial users.
Compatibility and safe degrading. If the user has disabled JavaScript or is using an old browser, the browser redirects directly to the image itself or to a given HTML page.
Link to us creates a page of banners that can be used by others to link from their website to your Drupal website. This allows users or writing contributors the ability to use consistent banners to link to your site.
The module creates well formed links with a title and alternate text. The link is SEO friendly as it uses the URL alias for the referenced page.
Currently, node and term pages are supported (anything else gives a link toward the front page.) Nodes also receive a link that give the users a very easy way to reach the Link to us page.

The Drupal 6.x version is minimally maintained. We are still looking for a co-maintainer for Drupal 7.x. A first version is available as a download on this issue.
