A Colorbox/Lightbox plugin for WordPress.
jQuery Colorbox features 11 themes from which you can choose. 
Works out-of-the-box with WordPress Galleries and <a href="https://wordpress.org/extend/plugins/nextgen-gallery/" rel="ugc">NextGEN Gallery</a>! (choose no effect in NextGEN settings)
When adding an image to a post or page, usually a thumbnail is inserted and linked to the image in original size. 
All images in posts and pages can be displayed in a Lightbox/colorbox when the thumbnail is clicked. 
Images are grouped as galleries when linked in the same post or page. Groups can be displayed in a slideshow within the Lightbox/colorbox.
Individual images can be excluded by adding a special CSS class.
jQuery Colorbox can also open linked content (external as well as inline) in a Lightbox/Colorbox.

jQuery Colorbox

This is the best WordPress plugin ever!



Best Plugin EVER!

I rarely install plugins on my client's websites but I do have a couple of "utility" plugins to make my life easier with development. This is one of them.

Have been using this plugin for years now and it is a great solution for any site that needs a colorbox effect.

Thanks for the plugin!

Easy to use and developer friendly.

Adds Colorbox/Lightbox functionality to images, grouped by post or page. Works for WordPress and NextGEN galleries. Comes with different themes.
