php - 图片无法在 Firefox 中加载

Question

我今天遇到了 FireFox 的问题，

当我想在 Chrome 上上传图像(并用 php 调整它的大小)时，它工作正常，然后显示图像。当我在 FireFox 上尝试相同的操作时，它不会随后加载图像。

这是加载错误的示例图片:

更新:

我调用这个 ImageProcessor 类

$ImageProcessor = new ImageProcessor();
$ImageProcessor->Load("/home/admin/domains/dev050.nl/public_html/web/media/uploads/".$rand.$ext);
$ImageProcessor->Resize(250, 180, RESIZE_STRETCH);
$ImageProcessor->Save("/home/admin/domains/dev050.nl/public_html/web/media/advertorials/".$rand.$ext,100);

函数:

/**
 * Resize
 *
 * @param int $width
 * @param int $height
 * @param define $mode
 * @param bool $auto_orientation houd rekening met orientatie wanneer er een resize gebeurt
 */
public function Resize($width=100, $height=100, $mode=RESIZE_STRETCH, $auto_orientation=false){

    // Validate resize mode
    $valid_modes = array("stretch", "fit", "crop");
    if(in_array($mode, $valid_modes)){
        $this->_resize_mode = $mode;
    }else{
        $this->showError("The resize mode '" . $mode . "' does not exists.");
    }

    // Aspect ratio resize based on width
    if(is_numeric($width) && !is_numeric($height)){
        $ratio = $this->_old_width / $width;
        $height = ceil($this->_old_height / $ratio);
    }

    // Aspect ratio resize based on height
    if(is_numeric($height) && !is_numeric($width)){
        $ratio = $this->_old_height / $height;
        $width = ceil($this->_old_width / $ratio);
    }

尝试清除缓存，也许它加载但在上下文之下？
