php PHP Uploading Images

[PHP programmer]

Hello, I am trying to upload images with php...I followed the instructions step by step and it just not working...The following error code is  Warning: getimagesize(): Filename cannot be empty in: ..............I copied the code from here.

Or you sure your server has rights to read / write the image ?

Under Linux, use

chown and chmod to adjust the rights.

Is your form your sending from properly configured ?

Your form must be multipart/form-data

<form action="upload.php" method="post" enctype="multipart/form-data">

For whatever reason the filename you're sending to getimagesize is empty.  If you copied that code without changing it then that could mean the file was too large.  The code they have doesn't really do any error checking.
