我正在编写一个 PHP 脚本来动态调整图像大小。图像 ID（来自 MySQL 数据库）是这样传入的：“http://localhost/getimage/1.htm”。

当我使用上面的 URL 直接进入脚本时，图像被完美地吐出。但是由于某种原因（仅在 Chrome 中），当我将该 URL 链接到标签时，它开始表现得很奇怪。当页面第一次加载图像加载正常，但随后加载栏旋转约 5 秒，图像突然消失，Chrome 显示“加载资源失败”错误。

有谁知道可能是什么原因造成的，如果是这样，如何阻止它？我认为它可能与 AdBlocker 有关，但我已禁用它并且它仍在发生。

干杯。

编辑：这是我正在使用的代码：

    header('Content-Type:'.$file['type']);
    header('Content-Length: ' . $file['bytes']);

    // Get size of original image
    list($o_width, $o_height) = getimagesize($file['src']);

    // Default width and height
    if (is_null($width)) {
        $width = $o_width;
    }

    if (is_null($height)) {
        $height = $width;
    }

    // Create image frame
    $image_p = imagecreatetruecolor($width, $height);

    // Generate image depending on source type
    switch ($file['type']) {
        case "image/jpeg":
        default:
            $image = imagecreatefromjpeg($file['src']);
            break;
        case "image/gif":
            $image = imagecreatefromgif($file['src']);
            break;
        case "image/png":
            $image = imagecreatefrompng($file['src']);
            break;
    }

    imagecopyresampled($image_p, $image, 0, 0, 0, 0, $width, $height, $o_width, $o_height);

    // Output
    imagejpeg($image_p, null, 100);
    exit;

As you can see I am setting the content types. If it was the htm extension, confusing it, would that explain why the image loads correctly, and then unloads itself?

this is not Chrome only, but IMHO it is wrong that you have this at the beginning: header('Content-Length: ' . $file['bytes']); because you don't know the actual file size, since you create the image on the fly with imagejpeg($image_p, null, 100); Try commenting out the header('Content-Length... line, it might fix it.
