1.6 -> 2.0 gallery management has changed – rather than just ‘attach’ images you now have this panel:

Once attached there, the gallery template should pull these. If by any chance you took the gallery template from 1.6.x, update it to 2.0.x format. You should see something like this in that template file:
$attachment_ids = $product->get_gallery_attachment_ids();
The 1.6.x version just pulled images attached to the post, rather than from our new panel.
If you have overridden all templates btw, its best to only move the ones you actually need to change – this avoids problems like the above.
Perfect, thanks! I always move all of the templates over because every time I do a Woo update, I normally get a bunch of bugs 🙁
Thats the downside I guess, but we usually list them in the changelog.
Its easier to update a few templates after major updates (the ones you change) that all of them.
