or Creative Commons images, free to use with attribution.
Whenever the latter is the case, such as in blog posts, we make sure to properly list the attribution and link at the end of the article. And, as often as possible, we link back to the original source even when the image states "No attribution required." We do this because, hey, taking good photos is an art, and making them available to the world is a generous act.
We appreciate, too, if you link back to the original owner, whenever you make use of photos from our site with the exception of photos belonging expressly to us. Please do not use these without our permission.
Please look on our Business & Website BuildingResourcespage for ideas of how & where you can find excellent images, often free, sometimes with payment. We have some favorites and we list them there.
