The by-product of search engine interactions - the records of what users have clicked as a result of a query - known as click through data'' is an increasingly popular resource of implicit feedback. Recently, however, the validity of such feedback has been questioned. However, the criticisms have focused almost solely on traditional web search, for which users are only presented with short abstracts to evaluate the resource before clicking - and creating the implicit feedback'' between the query and resource. In contrast other search types vary significantly in what the user is presented with and hence what is used to pass judgment and create the implicit feedback''. Of note is web-based image search interactions where the user is presented with a reduced thumbnail of the whole image. Image search click-through data has also been shown to have many potential uses in recent works, however, unlike traditional web search interactions there has been no previous research that has explicitly looked into its validity as implicit judgments. This work addresses this issue, comparing it to what has been discovered for traditional web search. While conceptually similar, the results of previous studies based on web search interactions can not be directly transferred to image search interactions due to the aforementioned difference in the summary displayed and used by the user in the decision to click.
