我使用php和js将图像上传到文件夹。我安装了XAMPP，一切都在localhost中运行。后来，我将我的代码上传到服务器，更改了路径，但它不起作用。
我检查了我的error.log文件中的路径，它们没问题，也获得了777的权限，这是它显示的错误：
＆＃34; PHP警告：imagejpeg（）：无法打开＆＃39; ./ uploads / Cartas / imagen_5923239258.jpg＆＃39;写作：在第152行和第34行的/ImageUploader/processupload.php中没有这样的文件或目录;
我的第152行是下一行：
imagejpeg($source, $destination, $quality); return true;
我的PHP代码在这里：
