服务器信息说 PHP 版本是5.2.10. 我们的fPDF作品是版本5.3，但不是版本5.2.8。

错误总是

FPDF error: Missing or incorrect image file:

问题是什么？

可能是这一行：

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

注释掉那一行，然后再试一次。如果它现在有效，那么您可能走错了路。我已经养成使用神奇的 "constant" 来“绝对”指定所有文件的习惯__FILE__。

如果 UST-LOGO 与您发布源的文件位于同一目录中，那么您可以将代码更改为：

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

编辑：这是引发该错误的 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阻止它）引起

我建议在您的代码（或 FPDF 代码）中添加一行检查file_exists($file)。如果返回 false，则仔细查看您的目录（在服务器上！）。如果返回 true，那么也许尝试用另一个图像替换图像，看看是否有效。

首先跳出来的是：

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

接近尾声。利用：

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

看看这个能不能解决。
