It's a combination of logos and rinks for the NHL that give you alternate team logos on gameday in your match screens. When you have both installed you will see the away team's alt logo in the titlebar and the home team's alt 'under' center ice.
It's a fun change from staring at the same logos over and over on every screen. 
You will still see the standard logos on your team pages but I have reworked those images (most noticably without the darn â„¢ marks
). Some images are clearer especially San Jose and Tampa Bay and for example Minnesota was made with a logo including the team name while mine was made from just the logo resulting in a much larger logo.There are two Tampa Ices included, the default has the 2004 Stanely Cup Champions logo and the 'alt' file has the same logo used for their alternate titlebar logo. You can use whichever you prefer by renaming the one you want to use to just 'Tampa Bay Lightning.png'

This is easiest to do with the logos, if there is a particular alt logo you'd rather have displayed on your team page as well just copy the version from the 'away' subfolder and use it as the logo in your National Hockey League folder too. Both are named the same. If you'd rather use a standard logo instead of an alt logo in your match titlebars just drag a copy of the logo in your National Hockey League folder into the 'away' folder in place of the one currently there.
