Hi, great question, Richard! Seconding Matthew's comment on WMF blog policy: At Wikimedia Deutschland we adopted the bottom notes for posts with multiple images[1]. As a general rule, we include attribution in the bylines[2].
Adding yet another aspect to sufficient CC licensing, let's not forget that CC deeds actually recommend linking to deeds[3], as exemplified here[4]. I particularly like Thomas' notion of not differentiating between attribution requirements for text and images. From my personal understanding of CC license terms, I agree. There is no difference, which indeed leads to the question: "How to deal with authorship attribution of dozens of authors (to pick a rather simple example) under CC-BY-SA in any convincing manner?" That is, "convincing" as in "intuitive and practical use cases". I sense that this is, first of all, an issue for Creative Commons licensing politics.
