下面是我的调整大小.php脚本。我需要安装 GD 库并这样做了,但我仍然无法让图像像以前一样处理我的旧服务器。这里 您可以看到错误报告创建了一个空映像,并显示以下错误:
Warning: getimagesize(http://stackoverflow.com/questions/19817599/../wp-content/themes/Explorable/panos/Pano__0000.jpg): failed to open stream: HTTP request failed! HTTP/1.1 404 Not Found in /home/go3de/public_html/wp-content/themes/Explorable/resize.php on line 16

您尝试调整大小的图像有多大?看起来它在抱怨内存不足?
尝试分配更多内存。
您可以尝试在页面顶部添加以下内容:ini_set("memory_limit","512M");...看看它是否有效。
想通了!我在最初的<?php
开始标签之前有一个空格,这导致了错误!啊!对不起,我是菜鸟!
