Stop paying for individual photos that cost upwards to hundreds of dollars each. Sure there are "free" sites out there but can you truly trust that those photos are actually being made available by the photographer? You can here. Each and every photo available here is taken by me personally, on one of my many outings around town or further from home.
For a one time $99 fee you not only get access to download and use as you see fit what is available upon sign up, but also any additional photos uploaded over time. The upload goal is currently set at around 25 per month, but you might get more or less in any given month.
