Oh so close! They want you to clear the float of every third element starting with the fourth element. That's the part you're missing. Your code clears the left of every third element starting with the first. Try this:

/* Write the CSS in the media query below */

@media (min-width: 607px) {
  img {
    float: left;
  }

  img:nth-child(3n + 4) {  /* Note the 4 here instead of a 1 */
    clear: left;
  }
}
