Howdy,

To install your fancy-shmancy BattyMaps spray, you will first need to find the right folder.  This, more often then not, can be found here:

C:\Program Files\Steam\steamapps\YOURUSERNAME\counter-strike source\cstrike\materials\VGUI\logos

Simply drag and drop the two files other then this read-me into that specific folder, and you should be fine.  I have already taken the liberty of coding the file to properly work with your system, rather then just my own.

To use your spray (some people may not know) simply go into your Options window within the game of your choice, navigate to the Multiplayer tab, and simply find it in the drop down menu provided.  You will have to reload the server you are in to have the changes take affect, if you are already playing in one.

Enjoy!
