Add inexpensive gutters hangers to lift and straighten sagging and bulging gutters. You'll restore good drainage too.
By the DIY experts of The Family Handyman Magazine:July / August 1999
Hook the gutter hanger under the front edge of the gutter and over the back edge. Then drive the hex head screw through the wood trim behind the gutter. The hangers will be stronger if you screw them into a rafter. Look for nailheads, which indicate rafter locations. Add new gutter hangers about every 3 ft. along the entire length of the gutters if the old ones have let go.
This style fits one common type of gutter and mounts from the top.
