If you are just starting out online and don't have any graphic editor installed yet, you will soon feel the need for it, not just for photo processing. Try the online version before you buy professional Photoshop (half the features you are unlikely to ever use). It's much cheaper, and for some tasks, you don't even need to learn Photoshop. I found a good series of https://tipsogram.com/ video tutorials on YouTube, and I have to say that I spent a lot of time on it. I assume that you also appreciate video tutorials: the brevity of narration, more or less pleasant voice of the author, loud sound.
