Biggest opportunity: Swap “after image” for “compare”. “after image” isn't earning its slot: you're not in the first 24 results for its own search. “compare” sits at #11 untagged, close enough for a declared tag to move it up. All five slots are taken, so one has to go.

How it's measured →3.8%
of downloads still active
At least 300 of 7.9K lifetime downloads are still running, above its category: the median Blocks plugin keeps 2.1%, across 1,580 plugins.
Downloads count every update, not just first installs, so older and more frequently released plugins read lower. Compare against other Blocks 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 3 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.

Update activity
How busy the existing users are, measured as downloads in the last 30 days for every 1,000 active sites. A spike means a new release everyone's pulling; a long, slow decline means an aging user base that updates less.

<strong data-start=”81″ data-end=”189″>After testing six or seven different image comparison plugins, this is the one that actually works 100%.It may not have tons of options, and honestly, it doesn’t need them. What really matters is that it is stable, easy to use, and simple to place inside containers so you can control the size and position exactly as needed.A clean, reliable plugin that does its job without unnecessary complications. Highly recommended.Y además soporte en español y si ven una petición lógica la implementan sobre la marcha.Muy grandes!

Perfect plugin to my needs, it does even more than I looked for (for example horizontal and vertical scroll). It works perfect with WP 5.5.3
Read on wp.org ↗ - ★★★★★ yeoric6.1y ago
Works very well in WP 5.5.1 (Sep 2020), does what it says. A very nice display option for images!
Read on wp.org ↗ - ★★★★★ berlincaspar6.1y ago
it just doesnt make sense, that the handle used to compage images disappears. Half of my users dont understand, that there is something dragable.

I really like this plugin
Read on wp.org ↗ - ★★★★★ Génesis6.3y ago
It is exactly what I was looking for, I would love if there was an option that allows “the white thing to drag” to always be visible. ♥
