It appears that the reason this page from a little-known website is able to rank amongst the bigger players is that the content itself is more focussed. It talks about how to name images for SEO, whereas most of the other pages are more general guides to image SEO—which all presumably mention the importance of naming images correctly, amongst other things.
Keep in mind, this will often mean shifting the focus of your business from more general to more specific products or services. For instance, instead of exclusively offering general home renovation services, you could consider specializing in "one day bathroom renos" or "custom kitchen makeovers." These more specific keyword phrases will likely be much easier to rank for, which will mean you can start ranking that much faster.
