I agree the upgrade.txt in the dowloaded archive is correct, and I acknowledged that in my post.
The Featured Photos code does work with member galleries if you modify the SELECT statement. My point is that Featured Photos on PhotoPost's own site includes member galleries, but the code as distributed does not, and there is no documentation on this... hence my comment on the documentation.
Code duly modified, no prob.
