Strict Standards Warning

[jgalea]

This is quite a minor bug.
On line #209 in wpthumb.php, the reset and explode functions need to be separated onto two lines.

The problem is that reset will attempt to take the function explode by reference and throw:
*Strict Standards:* Only variables should be passed by reference

This worked for me:

Before:

$this->_file_path = reset( explode( '?', $this->file_path ) );

After:

$exploded = explode( '?', $this->file_path );
$this->_file_path = reset( $exploded );
