Default Order by rand()

I have a query that looks like:

Code:
SELECT * FROM tbl_gallery WHERE fld_userid = $UserID ORDER BY RAND() LIMIT 4
I've read that using rand() isn't a good idea as it takes a lot of system resources. How can I rewrite the query to do the same thing without putting too much strain on my server?
