TwentyTen theme will break galleries with more then 3 columns (also 2 columns galleries look strange). This is a little fix.
TwentyTen, the default WordPress theme, removes the default dynamic styles from WordPress galleries, and adds some static CSS, so galleries with anything but 3 columns look broken. It?s not a WordPress bug, it is TwentyTen specific.
What is the problem? TwentyTen theme?s CSS sets all the gallery items width to 33%, so any gallery with more then 3 columns looks broken (the items are thrown on the next row), as the the total width of the gallery excedes the post width (4 x 33% = 132%).
This plugin adds some custom classes to galleries (eg. 4 columns: .width-25), and some CSS that fixes the width problem.
No configuration needed. Just upload, and install. The galleries will look as they should.

FancyBox Gallery integrates the FancyBox jQuery plugin into the WordPress 
gallery functionality. Simply use the gallery shortcode to display 
thumbnails in your posts with the option to link directly to the images (not 
the attachment template), and the plugin handles the rest. You get nice 
popups for the larger sized images, scaled to fit in the browser window, 
with a nice overlay effect.
<h4>Features:</h4>
<ul>
<li>Automatically scales large images to fit in window</li>
<li>Adds a nice drop shadow under the zoomed item</li>
<li>Groups related items and adds navigation through them (uses preloading)</li>
</ul>
FancyBox jQuery features, not yet implemented in the WordPress plugin:
<ul>
<li>Can display images, inline and iframed content</li>
<li>Customizable through settings and CSS</li>
</ul>
<h3>ToDo</h3>
<ul>
<li>Add a settings screen. Allow control of FancyBox display options.</li>
<li>Let user set their own CSS selector, instead of assuming the standard 
WordPress shortcode.</li>
</ul>
