yeah, that happens to me, regularly, too......I use the image search plug-in offered on the Firefox browser, but there may be other ways that are better.....scroll down below the "swimsuit", "torso", "smartphone" results and see if there is something further down the results page.....with the Firefox plug-in I use, several searches are offered, including google.....look around the entire screen for the various results and see if a name is repeated (not the photog or agency)....sometimes the instagram page for the person pictured shows.....often, it's just links to somebody's blog where they posted the picture just for content
there are other ways to search.......I suppose it's a bit of an art and I often don't get any results... others here are better at it!!
