您好我是亚马逊的新手并且对使用文件的想法很少。我正在尝试将缩略图上传到存储桶中。我可以在localhost上传图像，但我无法将其上传到存储桶中。我可以将原始图像上传到存储桶，这是我的代码

尝试设置正确的路径，在服务器根目录中上传缩略图。
$upload_img = Upload('image','uploads/','',TRUE,'uploads/thumbs/','200','160');
$upload_img1 = Upload('image','products/','',TRUE,'products/','200','160');
// Absoulte path where to upload thumnail
//$fileTempName12 = $_FILES[$upload_img1]['tmp_name']; comment this line
//$fileName12 = 'products/'.$_FILES[$upload_img1]['name'];
//full path of the thumbnail image
$thumb_src = 'products/'.$upload_img1;
$s3->putBucket("bucketname", S3::ACL_PUBLIC_READ);
if ($s3->putObjectFile($upload_img1, "bucketname", $thumb_src, S3::ACL_PUBLIC_READ)) {
echo "<strong>We successfully uploaded your file.</strong>";
}else{
echo "<strong>Something went wrong while uploading your file... sorry.</strong>";
}
