How to change your counter-strike spray using Wally.

This will only work for certain .bmp files.  All files won't necessarily work.  The .bmp's need to be a certain size.  The following sizes are your best bet.  64 x 128, 128 x 64, 64 x 64, 256 x 32, or 32 x 32 pixels

1. Download Wally from here.

2. Run Wally. 

3. Along the top you'll see a list of menus:     File  Edit  Wizard  View  Help     Click on Wizard

4. Click on HL Color Decal

5. In the top box select your half-life folder (default is something like C:\SIERRA\Half-Life)

6. Under select your modification select cstrike

7. Under Source Image, select File on hard drive and put the location of the .bmp file

8. Click OK

9. Your image should come up and you should see it.

10. Click on File, Save (Wally should save the file as "pldecal.wad"  in your cstrike directory)

11. Close Wally

12. Go Play some Counter-Strike
    (Be careful though,  Drat might tear you up, hehe)

Caution:  Going into the Customize screen in CS will make your tag go back to the old gay monochrome ones. 
You'll have to run Wally again to change it back.
