exlude some paths from sprite generation

I do have a hook at the moment which allows for excluding paths in regards to which images are compiled into sprite collections if thats what you referring to ( I forget what the hook is ) but many of my hooks/defaults will be settings ideally, I think what you mentioned is on my todo list

Never mind, right now I have the following hook, as you can imagine we already have some sprites, animated gifs, etc that should not be part of a sprite collection, I will be implementing the path based solution as well

/**
* Implementation of hook_sprites_images_ignore();
*/
function sprites_sprites_images_ignore() {
return array(
'./modules/color/images/lock.png',
'./modules/color/images/hook.png',
'./misc/farbtastic/marker.png',
'./misc/farbtastic/mask.png',
'./misc/farbtastic/wheel.png',
'./misc/powered-black-135x42.png',
'./misc/powered-black-80x15.png',
'./misc/powered-black-88x31.png',
'./misc/powered-blue-135x42.png',
'./misc/powered-blue-80x15.png',
'./misc/powered-blue-88x31.png',
'./misc/powered-gray-135x42.png',
'./misc/powered-gray-80x15.png',
'./misc/powered-gray-88x31.png',
'./misc/throbber.gif',
'./misc/progress.gif',
'./misc/druplicon.png',
);
}

I committed some of the changes, they should be available shortly. Hopefully I will have time to finish this off, we just got a few new clients today so I'm pretty swamped.

Where it would really get more complicated is rewriting the CSS taking the box model and parent selectors into account, personally I think that would just be a big unreliable mess but I have not really sat down to think about the approach much yet.

Thanks. I think there is a place for whitelist based images as well as blacklist.

But maybe ditch all auto-crawl of directories and move to a directive aproach as proposed at http://drupal.org/node/245602
