Until I can build a solution which works as well as what we had on the old site, a quick workaround which may keep you going in the short term (although still less than ideal) is to us the "Recent Activity" feed to identify comments made on photos.
The main problem with this approach is that the list grows very quickly because it shows all activity including all posts, media uploads and even likes - so by recent it really means very very recent.
