How can I change the thumbnail image size for Shareaholic Related Posts?

Follow

For WordPress, the default Shareaholic thumbnail width is 640px with dynamic height and no cropping. The thumbnail size can be specified programmatically by adding the following to your theme’s functions.php file with appropriate width and height variables -

add_image_size('shareaholic-thumbnail', $width, $height, true); 

Next steps:

  1. Each time you change Shareaholic’s thumbnail dimensions like this (or if you've just installed the Shareaholic Plugin), you will want to have WordPress regenerate appropriate sized thumbnails for all of your images. We highly recommend the Regenerate Thumbnails plugin for this purpose.
  2. Make sure to have Shareaholic run a "rebuild content index" (detailed instructions) so that the updates get picked up by Shareaholic Cloud.
