pictures

On my samsung galaxy tablet , I think every picture that I ever had put on my computer is here.  I have pictures of clayton and me on our first cruise, pictures of debbie  and I in washington dc, pictures that were on my "lost post".  I was trying to do a new post and I can't get any of  the pictures to go on my blog. I don't know much about computers.  I didn't put these pictures on my tablet. They just went on by themsellves, Also, this intelligent tablet downloaded all my sites, like my bank, everyone's blogs , everything in my favorites.



I have put lots of pictures on my blog so I cannot figure this out. The recent pictures I took are no problem.
