Biggest opportunity: Swap “image” and “image optimization” for “free” and “image resize”. “image” isn't earning its slot: it only gets you to #14. “free” sits at #11 untagged, close enough for a declared tag to move it up. “image optimization” isn't earning its slot: it only gets you to #11. “image resize” 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 →2.8%
of downloads still active
At least 100K of 3.6M lifetime downloads are still running, above its category: the median Performance plugin keeps 1.4%, across 1,103 plugins.
Downloads count every update, not just first installs, so older and more frequently released plugins read lower. Compare against other Performance 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.

What to do about it
- Swap “image” and “image optimization” for “free” and “image resize”. “image” isn't earning its slot: it only gets you to #14. “free” sits at #11 untagged, close enough for a declared tag to move it up. “image optimization” isn't earning its slot: it only gets you to #11. “image resize” sits at #11 untagged, close enough for a declared tag to move it up. All five slots are taken, so one has to go.
- One page off on “image”. #14 puts you just past the first ten results, where almost all the clicks stop. The gap to close is small.

Lo he usado y lo uso en varios sitios, principalmente para optimizar imagenes en sitios de noticias que muchas veces los editores por el “apuro” o por ignorancia, no editan las imagenes. Me resuelve problemas de carga y velocidad del sitio, ademas que la optimizacion ayuda en el SEO. Recomendado!!!!
