跳出的第一件事是：

$pdf->Image($file=$img, $x=null, $y=null, $w=150, $h=100, $type='jpeg', $link='');

快结束了。使用：

$pdf->Image($img, null, null, 150, 100, "jpeg", "");

看看这是否能解决问题。
可能是这一行：

$this->Image('UST-LOGO.jpg',25,10,18);

请将该行注释掉，然后重试。如果它现在起作用，你可能走错了路。我养成了使用神奇的“常量”
\uuuuu FILE\uuuu
来“绝对”指定所有文件的习惯

如果UST-LOGO与您发布源文件的目录相同，则可以将代码更改为：

$this->Image(dirname(__FILE__) . DIRECTORY_SEPARATOR . 'UST-LOGO.jpg',25,10,18);


编辑：以下是引发该错误的FPDF类的代码：

// line 1199
$a=GetImageSize($file);
if(!$a)
    $this->Error('Missing or incorrect image file: '.$file);

该错误只能由文件不存在（路径错误）或无法读取图像数据（文件已损坏或文件权限正在阻止它）引起

我建议在代码（或FPDF代码）中添加一行，检查
文件是否存在（$file）
。如果返回false，那么仔细查看一下您的目录（在服务器上！）。如果返回true，那么可能尝试用另一个图像替换图像，看看是否有效。
您可以发布一些代码来缩小范围吗？这两行在功能上是等效的，只是第一行还将值分配给一些（未使用的）变量。当然，duh。。。现在已经太晚了，很明显：-）我做了，但还是一样。FPDF错误：缺少或不正确的图像文件：C:\xampp\htdocs\exact\piechart.jpg
