How do you transfer pictures from computer to camera?

Make a file backup folder on your computer and copy all those photos to it and call it a by new name.
Now delete the bad or poor pixs from the orignal photo file . Select the pictues remaining one by one or other and send them to your camera which is listed as a drive. Or select each pix -copy them - and paste them to the camera drive storage. Practice this first- after making a file you copied all into.
