Well I'm and "old folk" and have no trouble with it. You simply must set aside some time and learn

There are literally thousands of tutorials you can find on Google, you tube

There are literally hundreds of "aps" you can download.

The the answer is right in your computer. Just about every computer there is has some sort of photo software bad as it might be, built right into it. Even the horrid Microsoft paint can be used. Google it

This gets a lot easier depending on what software is installed in YOUR computer. I can't help you because I do not know what is installed in YOUR computer. This is going to depend on who made it, when it was made, and so on.

Also, just about every digital camera on the planet comes with some sort of photo software.

And........if you go to the home pages of this very forum, there are some sticky threads on the subject.
