You might want to look at either Tile Plus or Gridder.

Now, there way to “force” three columns. The number of columns are directly related to the configured tile or grid image size of those template and the width of the content area that the theme has. Since most themes are responsive nowadays, it will also depend on how wide the screen is of the device being used to view the page and how wide the theme is styled to display on the device being used to view the page.

Hope that answers your question.
