Well, you can use this:
http://tools.wmflabs.org/catscan2/quick_intersection.php?lang=commons&pr...
which will give you one image. It has a bicycle and red flowers.
However, if you push the category depth past 7 you get false positives, because the category tree is horribly broken on Commons.

Why is it still, now in 2014, so hard to find images? We have categories and descriptions, but we also know they don't describe all that we want to find in an image. If I need an image with a bicycle and some red flowers, I can only go to the category:bicycles and hope that I'm lucky when browsing through the first 700 images there. Most likely, the category will be subdivided by country or in some other useless way that will make my search harder.
Where is science? Google was created in 1998, based on its Pagerank algorithm for web pages filled with words and links. That was 14 years ago. But what algorithms are there for finding images?
