I am trying to use the WP edit function on images to try to select the thumbnail that it displays on the blog roll page. But it does not seem to be working. Is there another way that I can manually select what part of the image that the thumbnail is created.
I’m not sure if you can change the crop position for each image individually but this plugin: http://wordpress.org/plugins/thumbnail-crop-position/ will help you to change it (at least for all images but maybe you can also select the images somehow). By default wordpress will center crop all images and you can’t change the crop position of the generated thumbnails manually.
