(fresh noob here.)
I'd like to change the size of the normal post's feature image above 624px. To make the image fit the entire site's width (960px max, like the default theme's setup).
So far, I've been successfully trying to reduce the witdh under 624px. To do so, I've been messing with the function.php at line 74 where I've changed the following line...
set_post_thumbnail_size( 624, 9999 ); // Unlimited height, soft crop
But it doen't seem to work when I change the width to 960.
Thanks for your help if you have any clue.
