1. A computer-implemented method, comprising: receiving, at a data processing apparatus, a first image search query and first image search results that are responsive to the first image search query, the first image search query being one or more terms in a first language; obtaining, by the data processing apparatus, translations of the first image search query, wherein each translation is a translation of the first image search query into a respective second language different from the first language; receiving, at the data processing apparatus, for each translation of the first image search query, respective image search results that are determined to be responsive to the translation of the first image search query when the translation is used as an image search query; providing first instructions to a client device that, when executed by the client device, cause the client device to present a user interface including: one or more of the first image search results responsive to the first image search query; and a respective cross-language search option for each of the translations of the first image search query, the respective cross-language search option for each translation including the translation and a preview of the respective image search results responsive to the translation, wherein each cross-language search result is selectable in the user interface, and wherein the preview of the respective image search results responsive to the translation is an image that is most frequently selected by users in response to submitting the translation as an image search query.
