STEP 4 : Change the highlighted code in RED with your photo URL from photobucket or where ever it is from. Save your template and your done. If you wish to reduce the images showing just simply delete the your photo URL that you want to be deleted and change the number you see after the banner. It is normally counted [0] to [5] if you got 6 images rotating and also change the var random.var banner= new Array()
