OK, tried it with the error checking if then statements.  I'm not getting any
results back from the database, but if I run the exact same command via the
command line I get back a good result from the db.

echo "select binary_junk, filetype from images where img_id = '92'" | mysql -u
root movies > /tmp/mysqloutput

The image ID is a unique number.  Only thing I can think is that something
changed regarding the mysql connection functions.  Saw that 4.2.1 had a fix for
4.2.0 regarding connecting to a mysql db, so maybe there are other issues.

Still find it funny that only the page that gets images is broken when all the
other pages are displaying correctly.
