Is it possible to apply Google search by image to a specific set of images?

Question

I would like to use google's 'search by image' feature to search a defined set of images (rather than the entire web) for matches. Has anyone done this previously or do they know if it is possible?

Answer 1

Yes, this is possible.

If you enter the image url, the search will be performed directly, however afterwards you can just type in additional keywords, or for example a domain.

If you want to search in a set of images that typically cannot be found by google, then it will probably not be possible.
