Biggest opportunity: Swap “lightbox” for “classicpress”. “lightbox” isn't earning its slot: you're not in the first 24 results for its own search. “classicpress” sits at #9 untagged, close enough for a declared tag to move it up. All five slots are taken, so one has to go.

of downloads still active
At least 700 of 12.8K lifetime downloads are still running, above its category: the median Uncategorized plugin keeps 0.6%, across 17,766 plugins.
Downloads count every update, not just first installs, so older and more frequently released plugins read lower. Compare against other Uncategorized plugins, not across the directory. wp.org reports active installs as the bottom of a band, so the real rate is this or higher.
This plugin shipped 4 releases in the last 12 months, and every existing install that updated counted as another download. wp.org publishes no split between first installs and updates, so we show the raw rate rather than guess at one.

wp.org is where the directory puts the plugin for that search. On merit is where it would sit if results were ranked on rating, support and updates, without the install boost. The last column is how far the wp.org position moved, from our first reading in the last 90 days to the latest.

Basically I wanted something that resemble the “Photos Viewer Application” from Windows where you can zoom and pan on large images. This is the closest I found for now.WP ImageViewer works nicely but there is a few things that prevent it from being perfect imo:1- When you zoom in an image, it doesn’t zoom where your cursor is but zoom at the bottom of the image automatically which is pretty annoying especially for large images2- Since it’s integrated to WP directly there isn’t any easy customization available, you cant change the position of arrows for e.g. that are not vertically centered as in every Lightbox I can think of3- Lightbox does not close when the user is clicking outside the image, I do like this in Lightboxes personnally4- I don’t think it’s possible to separate the images within a page from the same Slider/Lightbox. What I mean is, if you have let’s say 3 gallery of 5 images and use this plugin on all of them, you can’t have 3 separate Slider with 5 images, you end up having a giant Slider where you can loop back to image number 1 from the very last image of the page. It would be nice to be able to separate them5- Be able to change buttons icons would be nice even tho I guess it’s possible by doing some extra work

我的访客大多来自中国大陆，他们访问其他国家的网速会很缓慢。这就是为什么我一直寻找着能够自定义预览图和弹出大图尺寸的插件。其它的画廊插件通常不允许你自行设置这两个尺寸。但这个插件，它选择爬取原版Wordpress超链接指向的图片，这是一种相当巧妙的方式！而且它还提供了其它画廊插件所没有的缩放模块，我不敢相信这个插件目前的下载量只有仅仅300… Most of my visitors are from mainland China, and their Internet speed to other countries is very slow. That’s why I’ve been looking for plugins that can customize the preview image and pop-up large image size. Other gallery plugins usually don’t allow you to set these two sizes yourself. But this plugin chooses to crawl the pictures pointed to by the original WordPress hyperlink, which is a pretty clever way! And it also provides a zoom module that other gallery plugins don’t have. I can’t believe that this plugin has only 300 downloads at present…

Why is this plugin great? Does what it says on the box. Integrates seamlessly with standard WordPress functionality. Enhances the standard WordPress functionality without changing it – remove the plugin, and you’re back to standard WordPress without missing or broken blocks. Does not create unnecessary menu items and popups. Does not try to sell you anything. This plugin embodies the simplicity and functionality that WordPress should offer, as opposed to the cluttered, ad-infested, slow, and buggy alternatives out there.

Dead simple, super light weight and speedy. Pages load faster than other lightbox plugins. Love the addition of navigating via arrow keys and works beautifully on my touch screen monitor. Visually fantastic!
