S4 mini gallery contains 94GB of media on 8GB device

Hi, i have a samsung galaxy S4 mini. It has the usual 8gb internal memory and a 4gb SD card. Earlier icon came up stating I have low storage space on the device, I went to see what is using so much space and said applications is using 96GB and the biggest app culprit being the gallery. Amusingly my sd plus internal storage doesnt even come close to that size. I moved all the media to my SD yet nothing has changed.

Does anyone have any ideas what is going on?
