I'm using custom image dimensions in functions.php like this:

add_image_size( 'custom-size-thumbnail', 120, 120, true );

I uploaded some pictures with wrong orientation, so I used "edit" options to rotate them...

Problem is, that only original size pictures (full, large, medium, thumbnail) are regenerated (as a new file in the FTP directory - original picture.jpg, rotated picture-e1384125509778.jpg). My custom sized, however, are not :-( (no new file is created, theme is still loading one with wrong orientation).

Any idea how to fix this?


  • How are you regenerating Thumbnails? Mar 24, 2013 at 18:01
  • No special steps - just wp-admin built-in image editor does it itself when you modify picture...

  • WordPress doesn't regenerate intermediate image sizes. It only creates them on image upload/attachment post creation. Mar 24, 2013 at 18:46
  • Use a plugin like Simple Image Size to regenerate thumbnails manually (the plugin could do it in batch, don't worry).

Asked the same question here. There is an extra step to fix this, as answered in my question.


Regenerate Thumbnails or AJAX Thumbnail Rebuild should solve your problem.
