i know this has been asked a few times eg http://www.kriesi.at/support/topic/different-thumbnailsize-on-indexphp-archivephp-then-singlephp
but i just wanted to clarify the difference between feature image post sizes of the mainpage or archives from the single page.
i want to keep featured images on the mainpage and archives at 180px (im talking about the larger posts not the 2 column posts) but i when a person clicks on a post i want the single post featured image to be 100% width of the left column eg 560px or so.
in the functions.php it looks like i need to change the following
$k_option['custom']['imgSize']['M'] = array('width'=>180, 'height'=>180); // big preview pic for full sized posts
from this code it appears that the 180px size affects both the mainpage, archives and single page posts.
is there a way to achieve what im asking? i supposed its a bit like what happens in the habitat theme where single page posts have a larger featured image than in the archive or the mainpage...
