  已采纳

  40行代码有问题   header('Content-type:',$this->info['mime']);

  应该是 header('Content-type:'.$this->info['mime']);

  如何还是不行就试试这个

  <?php
  	class Image{
  	        /*内存中的图片*/
  		private $image;
  		/*图片的基本信息*/
  		private $info;
  		/* 打开一张图片，读取到内存中*/
  		public function __construct($src){
  			$info = getimagesize($src);
  			$this->info = array(
  				'width' => $info[0],
  				'height' => $info[1],
  				'type' =>image_type_to_extension($info[2],false),
  				'mime' => $info['mime']
  			);
  			$fun = "imagecreatefrom{$this->info['type']}";
  			$this->image = $fun($src);
  		}
  
  		/*压缩图片*/
  		public function thumb($width,$height){
  			$image_thumb = imagecreatetruecolor($width,$height);
  			imagecopyresampled($image_thumb,$this->image,0,0,0,0,$width,$height,$this->info['width'],$this->info['height']);
  			imagedestroy($this->image);
  			$this->image=$image_thumb;
  		}
  		
  		/*添加文字水印*/
  		public function fontMark($content,$font_url,$size,$color,$local,$angle){
  			$col = imagecolorallocatealpha($this->image,$color[0],$color[1],$color[2],$color[3]);
  			imagettftext($this->image,$size,$angle,$local['x'],$local['y'],$col,$font_url,$content);
  		}
  		
  		/*添加图片水印*/
  		public function imageMark($source,$local,$alpha){
  			$info2 = getimagesize($source);
  			$type2 = image_type_to_extension($info2[2],false);
  			$fun2 = "imagecreatefrom{$type2}";
  			$water = $fun2($source);
  			imagecopymerge($this->image,$water,$local['x'],$local['y'],0,0,$info2[0],$info2[1],$alpha);
  			imagedestroy($water);
  		}
  
  		/*输出图片*/
  		public function show(){
  			header("content-type:".$this->info['mime']);
  			$funs = "image{$this->info['type']}";
  			$funs($this->image);
  		}
  		/*保存图片*/
  		public function save($newname){
  			$funs = "image{$this->info['type']}";
  			$funs($this->image,$newname.'.'.$this->info['type']);	
  		}
  		/*销毁图片*/
  		public function __destruct(){
  			imagedestroy($this->image);
  		}
  	}
  ?>
