The easiest way of all would be to store the image inside the database
itself as a record, eliminating the need for random names entirely. Barring
that, however, your best bet is to have whatever application you are using
generate the random name. You will also have to check for duplicate entries
(perhaps by making the filename column UNIQUE), but collisions should be
very rare for any decent size (say, eight character) string of random
numbers and letters.
No telling what application you are using, but see man(2) mktemp for a
way to do it via a shell command, or do something like this in perl:
my @characters = ('a'..'z','A'..'Z',0..9);
my $ranstring = join('' => @characters[map {rand @characters}(1..8)]);
my $filename = "image_$ranstring.jpg";
