PS http://creativecommons.org/licenses/by-nc-sa/2.0/ states that "You must attribute the work in the manner specified by the author or licensor (but not in any way that suggests that they endorse you or your use of the work)." but in practice no one seems to specify a particular method. The ramifications of that practice are open for discussion.
In that case, displaying the photographer's name (or more commonly, whatever nick they use on flickr.com) on the description page of the image is probably adequate unless they have explicitly specified their desire for something above and beyond that.
There are other options too. Some people put their name in the image meta-data. Others use a watermark (but could one legally remove this if the license allows "derivative works"? hmm...), And then there is at least one guy always includes his name as part of the image title for his own "cc-by" photos.[1]
