here servlet

you see there images showing these images same. these images not images icons represents broken image when load browser doesn't support flash . ones see when browser doesn't support flash 1 talking about. not "f" icon represents broken image.

all images loaded url

getimagedetails.jsp?your_id=12 

so url doesn't point servlet, jsp. , if pointing @ servlet, servlet expects find id of image load in parameter product_code, you're passing parameter your_id.
