Not sure about attributing images. I found this wonderful photo on flickr (petra jane's photostream) and couldn't figure out how to attach a caption acknowledging the source so the best I could do was to put a statement in the description field under the title of my blog. The photo was on flickr as "some rights reserved" which seems to include attributing it as specified by the creator. I couldn't find any specifications so does that mean I don't have to attribute it at all? Help, I just want to do the right thing!
