What the license of the site has to do with the image ? The site is certainly not a derivative of the image, so I don't see the relation.
Whilst I'd never pretend to know anything about copyright, that would also be my interpretation. The "SA" in CC-BY-SA refers to derivative works - i.e. where you change, modify, etc the picture itself. Merely putting the CC-BY-SA picture next to text doesn't create a derivative work, so the text would not have to be CC-BY-SA'd
This is a matter of much debate and disagreement, as old as copyleft licenses. It's "strong" or "viral" copyleft vs. "weak" or "soft" copyleft. Traditionally, the FSF takes teh side of strong copyleft with the GFDL, and the CC crowd tends more towards the weak variant, implying that the share-alike requirement does not apply to "aggregate" works, only "true" derivatives. To me, that makes more sense in practice, even though it may be less desierable in principle. The distinction is tricky, however.
