Define new image in CSS file

There are many CSS file in ActiveWidgets. To add a new image then should I define it in images.css file? And should I make any modification in any other CSS file. Please, let me know.

You can add image rules to any CSS file or even to the html directly. Look at the examples in /examples/images - adding new/ folder in AW 2.0.2.

Thanks. I have got that. It's working now :)
