How to get my pictures out of my mac?

I take the pictures out of my iphone by just connecting it to my mac and exporting them through the Photos app.

Now I want to get them out of my mac and into my pc/harddrive (etc).

How do I do it?
Where are the pictures/videos stored?

In Photos select the pictures you want to move and drag them out of the Photos window. If you make a new folder on the Desktop you can drag them in to that and then move that to wherever you want it - if the PC is on the same network and appears in the Finder window you can drag them straight on to that.
