not sure i understand the logic/method as i upload images.
my theme uses custom fields to size images. i understand how to implement this feature but don't understand the logic to see if i can do something else.
currently when i upload an image it uploads three images sizes...
1) full size ( 500 px wide )
2) 150 px wide
3) 270 px wide
i am assuming that's because i assigned values in the settings > misc > image sizes menu.
can i upload automatically an additional size with the other three = 400 pix wide ? the new key name = detail
