I just got PS and I literally can't accomplish the most basic of tasks. For example, I open a picture from my computer and it just opens but I can't select it, resize it, etc. This is just an example- I can use Paint all day to mess around with images(obviously Paint can't really do much) and I've never seen a Paint tutorial in my life. It just makes common sense. With PS I see all these buttons and none of them seem to do anything important- but yet I can't even figure out how to do basic functions. What are the best online tutorials for beginners?
