How to use the Magic Wand to cut out pictures

On October 13th, I learned how to cut out a picture and put it on another background.

Using the magic wand tool, I cut out the white background on a picture of a man on a white background, as seen below. As you can see, his cut out is a PNG as there is a transparent background in the image.

I then opened up the background picture the man would be standing on.

Finally, using the move tool, I dragged the cut-out man onto the background.

Using Ctrl + T, I used the transform tool to make the man bigger on the background.

I then saved the finished image as a JPG to upload it onto Wix as an image without a transparent background.
