If your image is used on a Cookipedia article, the attribution should be placed in the click-through page containing the high-resolution image. These pages generally also hold the licence information, any extra annotation together with back-links to related articles, blogs, Creative Commmons image repositories etc.
Please do not place image attribution in the main article. This detracts from the main article and is not permitted on Wikipedia. Cookipedia's editors feel that we should maintain the same high standards.
