Since you have used "noindex, follow", they should still follow the direct image links.
I suspect it depends on whether the images are linked as <img src -- which they would be, if they're on pages of their own-- or as <a href -- no text, just the image file. I've got similar gallery pages myself. And I've seen robots treating the two differently, even when there's a jpg at the far end of both. Not just evil Ukrainians, but respectable* crawlers like the bing/msn imagebot.
Now, if you had a supplementary page that was tucked away somewhere, but human-accessible, and that page included <a href links to all the images that are normally linked with <img src ...
I've never heard about Duplicate Content in the context of images. Only text.
* Yes, OK, for a given definition of "respectable" ;)
