我这样调用图片是出来了 但是图片失真了 我应该如果处理呀?怎么样才能才能不要图片失真?

------解决方案--------------------
width="300" height="200" 
你限制了大小,当然会失真。
------解决方案--------------------
写了个JS处理方法,把这段代码放到head标签中试试。(没仔细调试,可能还存在问题,明天再看看)
HTML code
<script type="text/javascript">function getImgSize(img) {    var result = {};    var w = img.width;    var h = img.height;    if (w > 300) {        if (h <= 200) {            result.width = 300;            result.height = Math.ceil(parseInt(h) * 200 / 300);        }        else {            if (w / h == 1.5) {                result.width = 300;                result.height = 200;            }            else if (w / h > 1.5) {                result.width = 300;                result.height = 0;            }            else {                result.width = 0;                result.height = 200;            }        }    }    else {        if (h <= 200) {            result.width = w;            result.height = h;        }        else {            result.height = 200;            result.width = Math.ceil(parseInt(w) * 200 / h);        }    }    return result;}window.onload = function() {    var obj = document.getElementsByTagName('table')[0].getElementsByTagName('img');    for (var i = 0; i < obj.length; i ++) {        var wh = getImgSize(obj[i]);        if (wh.width > 0) obj[i].style.width = wh.width + 'px';        if (wh.height > 0) obj[i].style.width = wh.height + 'px';    }}</script><br><font color="#e78608">------解决方案--------------------</font><br>只需对 img 单边控制就能保持原来的比例<br><br>list($width, $height) =  getimagesize($result['lujing']);//可能需对$result['lujing']中的路径做适当调整<br><br>...<img  src="<?php%20echo%20%24result%5B'lujing'%5D;%20?>" echo alt="遇到麻烦 求高手解决办法" >$height*1.5 ?
