Really? Neither the word "instititution" nor "third party [website]" appear in the text of the CC license, so on what exactly do you base this very specific distinction just so narrowly fitting our behavior (no image attribution within articles, only on the image description page reachable upon clicking on the image), while not fitting anyone else doing exactly the same? The license requires only that the credit "be implemented in any reasonable manner". [Also note that the _text_ of our projects, while also licensed under CC-BY-SA, is licensed in way that explicitly states that a sufficient attribution is "[t]hrough hyperlink (where possible) or URL to the page or pages that you are re-using (since each page has a history page that lists all authors and editors)".]
Many of the images on Commons are from flickr which is CC 2.0 licenses. Not 2.5, 3.0, or 4.0 and there is no automatic upgrade from an older to newer version.
The CC 2.0 licenses do not say that a hyperlink is sufficient that is a v4.0 license. Many photographers are not making CC content available under 4.0 licenses as a result. So you have a problem in that much of your image content is licensed 2.0. Those running flickr2Commons upload bots are violating the license by upgrading it to v3.0 unless they are creating derivatives. None of the pre 4.0 licenses say that a hyperelink is sufficient for attribution. They all say that:
You must keep intact all copyright notices for the Work and give the Original Author credit reasonable to the medium or means You are utilizing by conveying the name (or pseudonym if applicable) of the Original Author if supplied; the title of the Work if supplied; to the extent reasonably practicable, the Uniform Resource Identifier, if any, that Licensor specifies to be associated with the Work, unless such URI does not refer to the copyright notice or licensing information for the Work
