This is a great theme but I think the generated thumbnails sizes are not the best.
I would like to know how do you have calculated the thumbnail sizes when you did the theme because I think that the sizes are not used properly.
I'm using a four column portfolio layout and the images lose quality when are re-sized, and I would like to change the generated thumbnail sizes, but I'm new on wordpress and I don't know where to edit all this setting.
On a four column layout the thumbnail container is 231px width and 172px height, but there is no thumbnail generated width this size, so it is using a different size, and as it has to adapt to the container size it's losing more image quality.
I'm wondering why you guys didn't have added this size to the generated thumbnail?
I want to change the different thumbnail sizes on the functions.php but as you've wrote on the documentation we also have to make some changes on the css, I would like to know what we have to change. Also I would like to know how do I "tell to Wordpress" what thumbnail to use?
