I'm using jQuery Knob and I'm wondering is there any way to put an image inside of knob instead of text, if not are there any other plugins similar to jQuery Knob which have this feature?
The quick answer is yes. The knob will work with an image. All you need to do is assign the class/id for the know to work on.
