我有一张图片,但它不会显示。我检查图像属性(右键单击并选择属性),我发现类型是text / html而不是JPEG图像。这是因为导致我的图像的类型不显示?如何更改类型值?我正在使用php ...



我在一个简单的html [img]标签中显示图像......



<编辑:



是的,我试过..如果我包含

 <?php header('Content-Type:image / jpeg'); ?> 

显示网址​​,非常奇怪吧?



我正在使用apache,图像由php代码生成...

 < img src =< ;?php echo bloginfo('template_url');?> /thumb.php?src =<?php echo get_post_meta($ post-> ID,image,$ single = true);?>& amp; h = 195& amp; w = 540& amp; zc = 1& amp; q = 95alt =<?php the_title();?> 


解决方案

  header('Content-Type:image / jpeg'); 

确保在执行任何输出之前调用header()函数,否则您将收到已发送的标头 错误。
