Samsung Galaxy S5--- pics can only be viewed using phone

[AC Question]

I have a 64Gig card in my Galaxy S5 and 1. newly taken photos can only be viewed on phone, cannot open when downloaded. 2. Videos cannot be played even though the thumbnail is shown.

Welcome to Android Central! Do you mean that if you copy the photo from the phone to your computer, you can't view the photo on your computer? And where are you having problems playing the video--on the phone?
