Something whacky happened in my transfer

Hi all, I have shifted my forum after a weeks testing to is main address. All is great, except the image upload now fails to work. I get the following message

Warning: imagecreatefromjpeg() [function.imagecreatefromjpeg]: open_basedir restriction in effect. File(/var/tmp/phpxRX8b5) is not within the allowed path(s): (/tmp:/var/htdocs/www_private/www.nihontokanjipages.com) in /usr/home/richt/www.nihontokanjipages.com/forum/uploadimg.php on line 275

I tried just deleting all the files, and reinstalling them, still the same. ANy clues or tips appreciated.

Cheers
