Watch Radar no. 93 · Quiet

Regenerate Thumbnails

By Alex Mills

What it does: Rebuilds image thumbnails, which helps after a change of theme or image sizes.

Why it’s listed: The most-installed plugin here, with one listed contributor and no update for 14 months. It still saw 64,288 downloads in the 30 days before our check. Most sites only need it after a change of theme or image sizes, and WP-CLI’s media regenerate command does the same job without a plugin.

Is Regenerate Thumbnails still maintained?

It has gone between one and two years without an update. That is an early sign, not a reason to move yet.

Quiet: No update for over a year.

Placements are our opinion, based on public evidence. Risk here means a plugin may not get a fix if a problem appears. It doesn’t mean we found a flaw, unless we show an advisory. Going quiet alone never puts a plugin in Replace now.
