the temp gauge only rises when the car is idle, like at a stop light or the heat is on, with the blower on. I have been told to flush the radiator, is that going to work or could it be a leak in head gasket?

1st off, without proper diagnostics you will not get a proper repair.
2nd, are your radiator fans working or not? You can usually hear when they come on and off.
3rd, have you even thought to check the water pump to see if it's working properly? My guess is that you have a bad water pump.
If it were a leaking head gasket, then you would have either anti-freeze in your oil or on the ground. Take your car to a technician that knows what he's doing for a proper diagnosis and repair.

It could also be a worn-out water pump. It would turn slower at idle and that may be enough drop in flow to cause a problem.
If either the head gasket or the pump is leaking you would need to add water to keep radiator level up. If you see antifreeze sludge on oil dip stick that points to head gasket woes. If you see a puddle on the ground by the water pump that is also a clue.

It still could be the thermostat, had that happen once, the new one was bad. Pull it out and run it without one, see if that helps. You may have to have the radiator rodded, flushing may help but it won't remove calcified build up. How old is the car? Could be a loose fan belt. Bad water pump. Fan bearings going out. Could be a number of different things.

Is the cooling fan working? This stops/starts from a thermostat in the engine water. This is not the thermostat you have had replaced, which allows engine water to circulate through the radiator.
Check both - the thermostat and the fan - is the fuse ok?

Once the engine coolant has been drained & then refilled, air becomes trapped within in the highest point of the engine. That means the head. Failure to remove the trapped air can cause serious damage to aluminium parts. If you have not checked the coolant level since the initial fill, likely the air has escaped & you'll find your rad has no or very little coolant.

If you have a fan clutch it may be out// (or) if you have elec fans they may be out(or) the relay to them may be out (or) the fuse to them may be out,(or) a wire to them may be broke(or) your radiator cap may be bad(or) you rad may be stopped up(or) your thermostat may not be working.(or your head gasket may be leaking. )(or) a radiator hose could be collapsing under pressure(or) you may have a bad temp gauge or sending unit. Good start dont you think?

If your oil level is constant, no water when you pull the dipstick and no excess water under the exaust system it is probably not a blown head gasket.
Flushing is cheap and a quick problem to eliminate.

it would be the radiator. if it where the head gasket you would see a cloud of white smoke coming out of your exhaust.
