With 100,000 active installs it has a real user base, though it lags well behind category leaders like Shortcodes Ultimate and Smart Slider 3.

Update Freshness

25/25

Last updated May 2026 and tested up to WordPress 7.0, so it is clearly being actively maintained.

User Rating

12/15

A 78 out of 100 from 95 ratings is decent but not outstanding, and the small sample size limits confidence in the trend.

Support Health

8/15

Only 2 support threads exist, both resolved, which is positive but also shows limited public engagement.

WP Compatibility

15/15

Tested with WordPress 7.0 and requires only 3.5.1, giving it one of the widest compatibility ranges in the category.

What It Does

FooBox is a responsive lightbox and modal popup plugin that opens WordPress gallery images, single attachments, and FooGallery albums in an overlay viewer with social sharing built in. It works automatically with the native WordPress gallery shortcode, so you do not have to add any markup to existing posts. The free version covers basic image lightboxing, while FooBox Premium adds HTML iframes, video support, and a WooCommerce product gallery mode.

Who It's For

This plugin is a solid fit for photographers, artists, real estate agents, and other visual-first site owners who want their existing WordPress galleries to open in a clean overlay without rewriting content. It pairs especially well with FooGallery if you want the masonry, justified, or album layouts that drive most of the targeted use cases. Sites that already have a dedicated gallery plugin and just need a polished overlay viewer will get the most value here.

Who Should Skip It

If you already use FooGallery, you may find the integrated lightbox sufficient and not need the standalone FooBox plugin. Anyone whose primary need is marketing popups, opt-in forms, or conversion-focused modals should look at Popup Maker instead, since FooBox is built for media viewing, not lead capture.

The Bottom Line

FooBox earns an overall quality score of 81.59 out of 100 and does one thing well: turning existing WordPress galleries into a smooth responsive lightbox. It is not the highest-rated option in the category and its user rating sample is thin, but its active maintenance and broad WordPress compatibility make it a safe pick for visual sites. Choose it if you already use FooGallery or want a no-fuss lightbox overlay for native galleries.

Related Plugins

Shortcodes Ultimate 93/100

Pick this if you want a much larger library of content elements, sliders, and lightbox options all from a single plugin.

Popup Maker 90/100

Pick this if your real goal is conversion popups, opt-ins, and modals rather than image lightboxes.

Photo Gallery by FooGallery 89/100

Pick this if you need the gallery layout engine itself, since it already integrates FooBox-style lightbox viewing.

Smart Slider 3 89/100

Pick this if you need full slide-based presentations and carousels in addition to lightbox functionality.

Autoptimize 88/100

Pick this if your real concern is site performance and asset optimization, not image presentation.
