In this tutorial, you will learn how to resize a photo on your Mac laptop or computer. It doesn't matter what kind of apple/mac computer or laptop you have. This works the same way on all of them.
I've just been having a look at your content. It's great to see someone who know's what he's talking about while simultaneously speaking with his actual (human) voice, and a very nice voice at that. I wish more RU-vidrs would do the same. Nice work!
