wp smushit add function to theme uploads


I have a few themes that I created for which I have added file uploads for header images. These upload to a theme folder. I am wondering if I could add WP Smushit functionality to these uploads and possibly to the custom uploads folder to smush all previously uploaded images.

I am pretty handy with coding - I just haven't looked at the code of wp smushit pro yet and figured I would speak with the experts first.

I think it would be a great feature to add the ability to smush all theme images, e.g. select the images folder in your theme and smush all.
