how to change the Atutor sites banner to a swf file
I'm using Atutor 2.2. Currently the site's banner is a jpg file named atutor_head.jpg located in /themes/default/images. I Want to change this banner to a swf file. Since it's a flash file, it can't be done only by changing the file. Because handling images is different from flash files in HTML. So can anyone help me, which file should I change and how?
