John, if you do a little searching on their website, http://library.bbhc.org/cdm/ you will find that they have thousands of photos. Over 150 just on Cody Wyo, and as others pointed out, they include, stock trains, waycars, engines, water tanks (old wood and new steel), as well as a wealth of photos of loading cattle and sheet at the stockyards (my primary interest).
Yes the initial image is small, click on it and it will open to a full width screen version, which you can zoom in or out. You will need to learn how to manipulate the features of the website to view the full size image. And no you cannot save a full size copy direct from the website. The download button will only generate a rather small image of about 50kb in size. Like many museum and library websites, they are protecting their holdings. I was able to use my print screen feature and photoshop to get some decent sized images for personal viewing. The clarity and details on some of the photos are simply priceless.
And yes they do sell images, that is how they support themselves, ie make the website available. This will take you to a page where you can find their fee schedule http://www.bbhc.org/research/rights-reproductions/ A nice size jpg or print for personal collections start at $15. For publication, they get much higher. Anyone who has every published an article or book is very familiar with the cost of working with museums and libraries who have photo collections. I don’t think the prices are out of line with what I have encountered at other facilities. I have paid $50 per photo at one such facility, so $15 is reasonable.
