assign each uploaded image a new filename. if you're using apache,
something like $ENV{UNIQUE_ID} will probably be good enough. then store
just the filename in the db.
you can also store the image directly in the db if you set up the field
as type 'blob'.
you can check to see if the filename already exists by doing something
like this:
print "$filename already exists." if -e $filename;
