My iPhone when sending a photo goes to mms so I turn it off to avoid extra charges. Maybe your Samsung has this feature and it's accidently off?

Make sure you have the green circle activated next to your MMS access point name.
If you haven't here's how you do it mate.
Go to settings> then click more settings in the wireless&network section> then click mobile networks> then Access Point Names> and make sure you have the giffgaff settings switched on.
