I am wondering how to search images sitewide? Is it correct to use "search" generator? Something like this: api.php?action=query&generator=search&gsrsearch=image_keyword&prop=imageinfo&iiprop=url

But I got pages contain "image" words instead image. What should I do to search images.

If you want a list of all images, use list=allimages. If you want to search image description pages for a certain word, use srnamespace=6.
