r=me, with some comments.

+        frame = docLoader() ? docLoader()->frame() : 0;

+    DocLoader* docLoader() const { return m_docLoader; }
+

The CachedResource::m_docLoader is non-zero only in some special cases (it should have a better name). Using m_request->docLoader() covers all cases we care about. These changes are probably not needed.

             // FIXME: I'm not convinced this case can even be hit.

I guess this FIXME can go now. We clearly can hit this case when maxImageSize is limited (plus it was not true even before). 

+        void setMaximumImageSize(size_t size) { m_maximumImageSize = size; }
+        size_t maximumImageSize() const { return m_maximumImageSize; }

How about maximumDecodedImageSize to avoid confusion between encoded and decoded size?
