Maybe their point was that you cannot filter the images, like by color, size, license, etc
But anyway, if I want to show somebody a picture of something it works perfectly As for the results, they are pretty comparable between searx, ddg, and googlag.
I would even say searx wins on this one because 1. It’s easier to navigate and open images 2. The nojs version of the search looks so much better than any other search engine
