If your camera is simply a camera with an SD Card. Use your computer to copy the files from the camera to the computer and then copy from the computer to the SD Card on your tablet! At least you have 2 backups of your pictures! I find the computer a lot faster and easier to edit photos and remove the bad shots! It is easier to use the computer to move photos into groups like Family, Kids, Work etc.
If your camera is one of the new Smart Cameras that automatically sends the photos to somewhere for you, check and see if you can find a group for that camera!
