Slenderbox

How well this listing is tuned to rank in WordPress.org search, on the factors an owner controls. Not popularity, optimization.

Directory rank vs rivals

wp.org popularity rank over time · higher is better · when a rival's line climbs above yours, they've overtaken you

How often this plugin actually ships. A steady rhythm is the maintenance signal a single "last updated" date can't show.

Share of active installs on each version of this plugin · 100% run the current release. Green is the current release; a big slice on older versions is a user base that has stopped updating.

Refined from the date this plugin crossed into its current band.

No paid tier is visible, so we don't put a figure on revenue or sale value: that would be guessing. The install base is a real asset to an acquirer, just not one public data lets us price. A small install base leaves thin data to model from. The recent download trend is too spiky to read.

   To start off, I have spent countless hours searching for a Lightbox plugin, compatible with an old verison of NextGen Gallery (version 1.9.13). Every plugin, that I have found, was missing something (e.g. wasn’t responsive as advertised or simply just didn’t work). This plugin gets the job done. However, Slenderbox have little to none options avaiable, but in my opinion, there is no need for them, plugin works excellent as it is. To sum up, Slenderbox works with and old version of NextGen Gallery (version 1.9.13) – just set effects in gallery options to none, is fully responsive, and there is no need for options.

   This is a simple and very smooth lightbox. It works perfectly out of the box, almost no customization is needed. It will display single images from a post or page in a lightbox. Very useful. This would six star plug in if it had a slideshow autoplay button and if it also had the option for adding social media icons in the lightbox. I am curious if there is a way to add this functionality, in particular the social media. May be in the next update?…

   Don’t work with galleries and don’t display captions, very bad for images SEO 🙁

   After trying a lot of other plugins, this one is the one. After activation it runs fast & smooth out of the box … and looks really good. Thanks for the great work!
