Oil Leak

While changing my gearbox oil today I noticed a few areas of oil under the car but cant work out where they come from. Oil looks fairly clean.
The picture I took doesn't show the oil very well. Its the light brown areas in the picture, the darker parts are totally dry.

Any ideas where the oil could be from?

thanks all

Have that on mine and can not find it for the love
