If you want to use a different graphic than the default stars for review ratings, follow the steps below:
1. You will need 2 graphics: One with the rating images highlighted (i.e. on) and one with the graphic images unhighlighted (i.e. off). The graphics must contain 5 elements for ratings, each equally spaced apart.
2. Upload the highlighted / lit one to the directory (and filename):
reviews/images/review_on.gif
3. Upload the shaded / dark one to the directory (and filename):
reviews/images/review_off.gif
4. If the image is not 75 pixels wide, then you will need to edit the file:
reviews/css/feedback.css
and change the ".feedbackBG" section from:
width: 75px;
to however wide the images are that you are using.
You also need to change the field for 'Number of pixels' on the configuration screen of the Admin section of the Reviews Module to the appropriate number.
