I took a screenshot and fixed it up a little where do I put it to use it as my spray?

it has to be mulitples of 16 up to 192 on wally and i belvie i think 224 with decal converter..
So basiclly heres the process....
1. You get the pic you want
2. You edit it to how you want it
3. You put it down to muliples of 16 (shown above)
4. You save it as Jpg formatt
5. You open it on wally/decal converter (shown above also)
6. You save it as a wad on your desktop
7. You go to
C:\Valve\Steam\SteamApps\your email\condition zero\czero (it may be in program files for me its not but it can be)
8. You delete your old tempdecal !!!
9. You rename the wad file you made tempdecal
10. You copy and paste or however you want to do it into your folder shown above
11. You right click it and go to properties. Make read-only.
12. restart cz
13. Your done
