Several years ago, yes. In the last 3-4 years, this has evolved right along with the search algorithms. Images open the door for increased SEO-friendly content, beyond just the alt tag, working in concert as each component makes each other component more relevant.
Lawn images are good. Written lawn content is good. Lawn Images + Written Lawn Content legitimately becomes one of those "the whole is greater than the sum of it's parts" scenarios.
If you don't place more weight on image importance, you leave a large amount of SEO on the table:
-image file name
-image file folders with relevant keyword naming (ie, a lawn-care folder with -----lawn-care related and named images within it)
-related content directly near the images (contextualizing an image's reason for being, if you will.)
-anchor text to linked images
- image titles (although having gone the way of the meta keyword tag, it's up to you to decide if you want to put in the effort)
- and rapidly growing in importance? social sharing
