Answer 1

What error code do you get?
echo $_FILES['image']['error']
0 => 'There is no error, the file uploaded with success'
1 => 'The uploaded file exceeds the upload_max_filesize directive in php.ini'
2 => 'The uploaded file exceeds the MAX_FILE_SIZE directive that was specified in the HTML form'
3 => 'The uploaded file was only partially uploaded'
4 => 'No file was uploaded'
6 => 'Missing a temporary folder'
7 => 'Failed to write file to disk.'
8 => 'A PHP extension stopped the file upload.'
