Grid help.
Okay so I am trying to learn and start creating my own avatars sigs and wallpapers in photoshop. I have read quite a few tutrols watched some videos and googled but have not come up with an answer. In this video the guy has it set so everytime he creates a new images in photoshop it automatically splits or shows a 3x3 grid no matter the size. Watch this video and if you know how he does it please let me know.
