Note to competitors:was is that hard to think about it?
Note to author: Great work, you can make it king if you can add feature regenerate only broken image sizes
Saved me half my life in a 100k media library.
I’ve tried everything they say to do and this plugin unfortunately just does not seem to work with 4.7.4.
Doesnt have 4.4.1 bulk generation support. But you can generate thumbnails one by one.
We had to change a few sizes and regenerate many images in a short time, excellent plugin.
Will improve the notification to terminate the regeneration process of the thumbnails for the user log is reached as to distract.
