이미지가 자동으로 바뀌는 자바스크립트인데요
현재 이미지(image1.jpg) width가 이미지사이즈 크기의 px로 되어있는데
width(image1.jpg)를 100%로 하고싶으면 어디소스를 수정해야하나요?

슬라이드 제이쿼리때문에 고민하시나보네요
보통 js에서 이미즈 size를 구해서 width로 지정할텐데
코드를 통째로 해석하거나
width:100% !important로 변경안되게 고정시키거나 해보시는게 어떨까요
진
스타일로 변경해보세요
#slideShowImages2 img{width:100%}

maxslidewidth함수
두개중 하나가 이미지 사이즈를 받아와서 사이즈를 지정해주네요
