Low resolution means that the images on this site are saved in a low quality mode so that they will load quickly  for you to view. 
They are very small compressed "JPEG" images. Often times they will appear to be out of focus due to the low resolution. 
The original raw files that will produce your final prints are of MUCH better quality than what you see here. Be assured that any prints you order from Vermont Sports Images will be sharp. We would never attempt to sell you a photo that is not in focus.
