Ok first lets id the parts, Pic. 2 is your gas valve. Pic. 3 right top is your fan and limit switch.
In pic. 5 there is a small wire entering the furnace. This wire looks like it's tight against the metal on the top side of the hole. Check that out to make sure you don't have a bare wire touching the metal furnace.
Leave the door off the furnace so you can see the burners. Now when you turn the stat down and its still going, take and tap the side of the gas valve, this could let us know if we have a sticky gas valve.
If it still on then in pic. 2 you have 3 wires on the front of the gas valve,
take a pair of pointed pliers and take the left hand wire off and see if it turns off. if it does then the problem is in the stat or wires going to the stat.
This unit looks pretty rusty, stand in front of the furnace and have someone
turn the furnace on. Get down so you can watch the flame on the burners.
When the blower comes on is there any flame floating around. If there is you need to have the heat ex-changer check because you could be getting
Are there any other bare wires in the furnace?
There is a wire going from on top the gas valve over in front of the fan switch and it keeps going to the right, where does this wire go?
Start checking out these things and get back with me. Paul
