How we can insert background image on the registration form

Answer 1

Oh yes I forgot url, no wonder it looked so weird to me at first.

Answer 2

CSS :
form {background: myImage.jpg no-repeat}

This is wrong, use visph's answer instead.

Answer 3

@cheeze:
Isn't it better as this:

form { background: url('url/to/my_image.jpg') no-repeat; }

;) :P
