reGenerate Thumbnails Advanced

5 stars for this plugin that not only regenerates the thumbnails (which is what is supposed to do), but also lets you choose which ones you want to regenerate, which ones you want to delete, and it even lets you create new thumbnails!

Does what it says and more


Great plugin, still checking the site for now. But 250k previews were cleaned, which was caused by a poorly set template that generated 40 previews from each file. Many thanks for saving lot of hours work.


Top plugin, fast and reliable cleaning

Regenerate thumbnails quickly and easily, including forced regeneration; very useful when changing a theme or adding new thumbnail sizes.
