You are purchasing high resolution, non-watermarked JPEG images with a non-exclusive, non-commercial license. You may email, post online, share, make prints, calendars, etc, provided you do not resell them or claim ownership. The images print great up to at least 8x10 (and usually much larger) depending on cropping. Contact me directly at adam@adamlyonphotography.com to discuss commercial usage of images, exclusive licensing or bulk pricing.
