Thanks very much for your help.
The version of MySQL on my host is 3.23.22-beta,
I changed
mysql_fetch_assoc to
mysql_fetch_array in line 111 "includes/db_mysql.php". like you said in your reply.
Now the image categories page loads up but at the top there is some text saying
Warning: Array to be filled with values must be passed by reference. in ./includes/functions.php on line 284
