var str = ' <img src= "IMGP7406.JPG " width= "300 " height= "250 " style= "width:100px;height:100px "> ';

var reg = /(height|width)=[ " ']\d+[ " ']/gi;
alert(str.replace(reg, " "));
[解决办法]
Regex.Replace(str, @ "width=[ ' " "]?\d+[ ' " "]?\s*height=[ ' " "]?\d+[ ' " "]? ", " ");
[解决办法]
Regex.Replace(a, "\s+width=[ " ']?\d+[ " ']?\s+height=[ " ']?\d+[ " ']? ", " ");
