I think the more useful question is not what percentage of the images are non-free, but "what percentage of the articles contain no non-free images?".
English Wikipedia has 1,993,145 non-redirect pages. Of those 1,453,071 are not disambigs and are over 1000 bytes long. Of those, 292,871 have one or more non-free images.
So 20% have non-free images.
Considering that a lot of pages don't have images at all.. (this isn't so easy to count since little template inserted images still count as images, but I don't think we ought to be counting them while trying to figure out how many articles are illustrated).
