Stop Generating Unnecessary Thumbnails


Big Update

Since version 3.0 or higher, you can now regenerate thumbnails of your existing images!

When you upload an image using Media Uploader, WordPress generates multiple copies/thumbnails of that image. By default, WordPress generates 4 thumbnails-

  • Thumbnail
  • Medium
  • Medium-large
  • Large

But along with this, theme and plugin developers can register their own thumbnails. Although they may be on purpose, but sometimes they remain unused.

Think about it, unnecessary additional images are eating up your server space and slowing down your site!

Sounds like a problem? What is the solution then?
This is where our plugin comes into the picture. Just install the plugin and choose which of the imaze sizes you want to prevent from generating.

  • Works with any plugin and theme.
  • WooCommerce compatible.
  • Multisite compatible.
  • Super easy to install and configure.
  • It’s free and always will be.

根据我使用一段时间的经历,这款插件的功能还是很不错的,可以方便的限制不需要的缩略图尺寸,并且可以批量重新生成缩略图。运行效率也不错。 有一点遗憾的是,插件有时候会失灵。 例如,我现在使用的主题本身有9个尺寸的缩略图,很浪费空间,使用Stop Generating Unnecessary Thumbnails之后可以方便的禁用某些规格。 不过,会有失效的情况。 有时候重新修改了主题的外观或源代码之后,必须重新进入SGUT去Save Settings,否则,上传新图片时,又会自动生成全部这9中规格的缩略图。 程序方面我是外行,原因搞不清楚。希望开发者进一步解决吧。

Just a warning to anyone attempting to use this, test it on a completely backed up site first. Most of the image files in my uploads folder were somehow deleted by this plugin. Likely incompatible with certain plugins and possibly with the Enfold theme.

Thank you! This plugin is problem solving. I have 19 thumbnails before and now I just have 5 thumbnails.
