Yes. To use an arduino to program the esp8266 you must remove the avr ship from the socket.
The arduino board is nice because it gives you the 3.3 v output and has 2 ground pins that come in handy for flashing.

If you have an esp-12 the flashing circuit will be a bit different

Flashing circuit should look like what is shown below.

The rx, tx and power pins on the arduino should be used.

Interesting, I'm seeing GPIO0 pulled low
