How to Oekaki?, Click "Draw" in the top banner and use one of the included applets to draw directly in your browser, or use Paint Tool Sai with Binary tool, or use AZPainter2 which has everything that ChickenPaint and Shi-Paint has but on a standalone program via upload feature.
NOTICE If you are using chrome then you must use either the "ChickenPaint (HTML5)" applet or standalone AZPainter2 program.
You cannot use the Java Applets as chrome after update 45 stopped and discontinued java support.
If you want to use a different applet you must use a different browser, use AZPainter2, or PaintToolSAI (Via Binary tool)
