教你在网站中实现图片不变形等距离缩放

<script>
<!--
function DrawImage(ImgD,FitWidth,FitHeight){
var image=new Image();
image.src=ImgD.src;
if(image.width>0 && image.height>0){
if(image.width/image.height>= FitWidth/FitHeight){
if(image.width>FitWidth){
ImgD.width=FitWidth;
ImgD.height=(image.height*FitWidth)/image.width;
}else{
ImgD.width=image.width;
ImgD.height=image.height;
}
} else{
if(image.height>FitHeight){
ImgD.height=FitHeight;
ImgD.width=(image.width*FitHeight)/image.height;
}else{
ImgD.width=image.width;
ImgD.height=image.height;
}
}
}
}
//-->
</script>

<IMG SRC="<%=rs("img2")%>" border=0 onload="javascript: DrawImage(this,180,160);">
