Upload image as progressive JPEG

Hey guys!

I want to upload all images (listing images, account thumbnails) as progressive JPEGs. Can you give me some pointers - what files should be changed and where to add code.. As I understand it's done with imageinterlace() function...
Would be awesome if you could help!!

Regards,
