I have not seen your response to my analysis that conluded that quotations are more problematic than images.
If I understood correctly, you argue that quotes are embedded in the text while images are kept in separate files, thus GFDL is not inherited by the photo but is inherited by the quotes. This is incorrect. Derivative work are required to be under GFDL; what constitutes a derivative work is defined by copyright law. The technical detail that text and images are typically kept in separate files is irrelevant; illustrating an article by adding a picture is a classical case of a derivative work. Moving quotes out of the main text and then "including" them somehow is a technical gimmick that doesn't change anything: adding a quote also creates a derivative work.
Including quotations would indeed be a technical gimmick, and our server would provide a single HTML file, a derivative work. That images are separate, however, is more than a technical detail; it's an important feature of HTTP that's used in other ways. Our copyright notice at the bottom of the page even refers only to "text"; a result of this feature is that the text is easily separated.
