Companies Using Responsive Lightbox & Gallery

Responsive Lightbox & Gallery has "gallery" in its name. On most sites in our October 2026 crawl, though, it's a lightbox. A domain counts here when its pages carry the plugin's settings object, rlArgs, or load its front-end script. That gives 48,283 live domains, 3rd of 29 in Photo Galleries, with 30,029 matched to a company. The plugin is free and actively maintained by dFactory: version 2.7.10 shipped on 5 October 2026.

A lightbox first

I opened 45 random live domains. 43 home pages loaded the plugin, and none of them showed one of its galleries. Three had image links tagged to open in its lightbox. Because the settings object is printed in the page, it also shows which lightbox each owner chose: of the 39 pages where I could read it, Swipebox was set on 16, prettyPhoto on 10, Nivo on 5 and TosRUS on 4. GLightbox, imagelightbox, Featherlight and fancyBox had 1 each.

Sales signal: don't sell gallery or portfolio products off this list alone. What it reliably tells you is that a WordPress site shows images and its owner bothered to install a lightbox.

Flat since July

The chart reads 42,279 in June, 46,635 in July, 47,063 in August, 47,952 in September and 48,283 in October. The June to July step comes from our side: the domains we crawl turn over every month, with dead sites dropping out and new ones added, and our detection widened over the same months. 3,935 domains have dropped the plugin on at least one hostname since we began tracking it in March 2026; when I rechecked, 547 of them still loaded it on another hostname.

"None of the 43 home pages that loaded Responsive Lightbox & Gallery showed one of its galleries. People install it for the lightbox." - Emma Davies, Data Analyst at TechnologyChecker.io

Sales signal: treat it as a stable base of about 48,000 domains. Listed on wordpress.org since July 2013, with 100,000+ active installations on its listing, it's a mature plugin rather than a rising one.

Who the customers are

65.68% of matched companies with a known size have 1 to 10 employees and 21.95% have 11 to 50. Only 6.77% were founded in the 2020s and 37.69% before 2000, an older base than Photo Gallery by 10Web's (34.09%). There are 254 companies above 1,000 staff. Bacardi, Goya Foods, the Panama Canal Authority, St George's University Hospitals and Zuyderland run it on their main sites. At USC, Northeastern and McMaster it sits on a single school's or department's site.

Sales signal: at universities and hospital groups the buyer is the team that runs one site. Pitch the department, not central IT.

A German tilt

The United States has 6,007 matched companies and Germany 3,802, about five German companies for every eight American ones. On Photo Gallery by 10Web's profile it's roughly one for every four, and on NextGEN Gallery's and FooGallery's about two for every five. Switzerland (504) and Austria (375) take the German-speaking total to 4,681. The Netherlands (1,542) and Poland (1,316) also rank higher here than on Photo Gallery by 10Web's profile, and Borlabs Cookie, a German consent plugin, runs on 2.28% of domains.

Sales signal: for German-language agencies, consent vendors and hosts, this is the best-qualified of the four gallery-plugin lists we publish, because Germany's share is higher here than on the other three.

Next to the other gallery plugins

There's no migration table on this page. 6,570 Responsive Lightbox domains also run Slider Revolution today, 13.78% of the 47,682 we checked for co-installed technology. Photo Gallery by 10Web is on 678, NextGEN Gallery on 260 and FooGallery on 213. For each pair, about nine in ten domains ever seen with both still run both, so none passes our switching tests. A lightbox and a gallery plugin do different jobs, and sites keep both.

"About nine in ten sites that ever ran Responsive Lightbox beside another gallery plugin still run both. They're complements, not rivals." - Emma Davies, Data Analyst at TechnologyChecker.io

Sales signal: gallery-plugin vendors shouldn't position against it. Sites running it beside a slider and a gallery plugin are candidates for a speed or consolidation pitch.

The stack around it

Shares are of the 47,682 live domains we checked. WordPress is on 99.78%. Elementor is on only 11.35%, about half its rate on Photo Gallery by 10Web's domains and a third of FooGallery's (34.34%). Underscore.js is on 88.55% because the plugin's front-end script loads WordPress's own copy as a dependency. Google Analytics runs on 52.99%, and CookieYes (7.23%), Cookie Notice (5.38%), Complianz (4.4%) and Borlabs Cookie (2.28%) handle consent.

Sales signal: Google Analytics on more than half the domains, plus a European tilt, makes this a reasonable list for consent and privacy-friendly analytics vendors.

Upkeep

The plugin prints its version in its script address. Of the 31 sampled home pages where I could read a plausible version, 8 ran the current 2.7.10, 9 more were on an earlier 2.7 release and 14 were older than that, going back to 1.7.2. Dropping it is rare by comparison: 3,935 domains since March against 48,283 live.

Sales signal: 14 of 31 sites on a release older than 2.7 is a decent opener for WordPress maintenance and security offers. Lead with the outdated plugin, not the gallery.

What it costs

The plugin is free. dFactory's extensions page (checked 14 October 2026) lists add-ons at $29 each, such as Masonry Gallery Pro, Justified Gallery and extra lightbox scripts, Remote Library Pro at $19 and a Photo & Art Bundle of all of them at $69. On wordpress.org, 2,003 ratings average 4.9 stars.

Sales signal: with a $69 ceiling, the plugin's own upsell is small. The money around these sites is in hosting, maintenance and the rest of the stack.

Key takeaways

1. 48,283 live domains, 3rd of 29 and 2,295 behind Photo Gallery by 10Web.

2. A lightbox in practice: none of 43 sampled home pages showed one of its galleries.

3. A German tilt: 3,802 German companies to 6,007 American.

4. Older businesses: 37.69% founded before 2000.

5. It sits beside gallery plugins rather than replacing them.
