LightPress Lightbox (WP JQuery Lightbox) Plugin

The LightPress Lightbox was formerly the WP JQuery Lightbox. Along with the name change, we’ll be doing signficant development on this plugin in 2024, including the addition of additional, modern lightboxes (both free and pro). We’ll still continue to include, support, and enhance the original lightbox!

This plugin adds a simple, lightweight lightbox for viewing images. See demos here.

Features

• Automattically detect images so they open in a lightbox with no need to adjust markup.
• Works seamlessly with WordPress core images and galleries, and galleries from many plugins.
• Play or puase slideshow within lightbox.
• Enhanced mobile support with swipe gestures on touch devices, improved scaling to maximizes use of screen space, and live adjustment to the browser window and orientation of your phone.
• Browse images with your keyboard: Arrows, P(revious)/N(ext) and X/C/ESC for close.
• Admin panel to configure options. sv
• Localization support.
• Lightweight and fast.

Background and Thanks

Special thanks to Ulf Benjaminsson, who created this plugin and maintained it for many years.

The original WP JQuery Lightbox included with this plugin lets you keep Lightbox 2 functionality but sheds the bulk of the Prototype Framework and Scriptaculous Effects Library. Warren Krewenki ported Lightbox to jQuery and this plugin is mostly a wrapper to his work.

1. Upload the wp-jquery-lightbox-folder to the /wp-content/plugins/ directory
2. Activate the plugin through the ‘Plugins’ menu in WordPress
3. Check out the jQuery Lightbox-panel in your admin interface for usage details and configuration.

How to Use:

1. With WordPress built-in gallery: [gallery link="file"]

2. All galleries in a post make a single slideshow. To create separate slideshows, use group:

   [gallery link="file" ids="1,2,3" group="mon"] [gallery link="file" ids="4,5,6" group="tue"] 

3. You can manually add a rel="lightbox" attribute to any link:

   <a href="image-1.jpg" rel="lightbox" title="my caption">image #1</a> 

   Note the use of title-attribute to set a caption

4. To manually group sets of related images, follow step 3 but additionally include a group name in the rel attribute:

   <a href="image-1.jpg" rel="lightbox[roadtrip]">image #1</a> <a href="image-2.jpg" rel="lightbox[roadtrip]">image #2</a> <a href="image-3.jpg" rel="lightbox[roadtrip]">image #3</a> 

5. You can use the data-download attribute to set a custom download link:

   <a href="image-medium.jpg" rel="lightbox" data-download="image-superlarge.jpg"> [...] </a> 

6. To disable lightboxing of an image link, just set any other rel-attribute: rel="nobox"

7. Keyboard support: Arrows, P(revious)/N(ext) and X/C/ESC for close. Swipe left / right on touch devices.

8. Infinite-Scroll and similar “endless pages”-plugins should call doLightbox(); whenever it loads new content. Check your plugin for a setting
   named “callbacks” – code that is called after each new page is loaded. Add this line;

   if(typeof doLightBox !== 'undefined' && typeof jQuery !== 'undefined'){ doLightBox(); } 

9. On the server side you can apply lightbox to any content by running jqlb_apply_lightbox($your_html_content, "any ID"); It returns a string with all image links lightboxed, grouped by "any id".

Trouble shooting:

If you have problems with WP jQuery Lightbox, please make sure you try these steps before asking for help. If you ask for help and I find any of these steps would fix the problem, I will just link you back here to do the work yourself.

1. Make sure your site is not throwing any javascript errors. Use your browsers javascript console to find out.

If you’re running a custom theme:

1. Make sure you have wp_head(); just before the closing </head> tag of your theme, or you will break many plugins, which generally use this hook to reference JavaScript files.

2. For the same reason, always have wp_footer(); just before the closing </body> tag of your theme.

3. Many JavaScript optimizers, combiners, minifiers, etc. conflict with wp_localize_script, used to configure this plugin and many others.

• If you have problems with jQuery Lightbox; first disable all JavaScript-optimizing plugins. (Optimize Scripts, W3 Total Cache, WP Minify etc)

• If you develop JavaScript optimizers for WordPress, please play nice with the default API…

• More info about this issue

Lastly:

1. Disable all other plugins, one at a time. Try the lightbox between each.

2. Revert to the default theme. Did it help? Fix your theme.

3. Search the forums for similar symptoms.
