How do I apply a patch file?
It is obvious latest colorbox plugin needs patching because even with drush install it is not working to load images and I've been at it all day, literally.
So found this http://drupal.org/files/patch-colorbox-1_3_21-2.patch which is recommended for the drush install of colorbox plugin with only the one colorbox folder.
But where and how do I patch it?
Very kind volunteers have been trying to help throughout the day but I am yet to get this fixed.
