saving a picture from the web???? PC= right click, and save picture. Mac= I don't know yet.
Hold the control key (ctrl +click is the right click) down while clicking on the image.
The mouse driven Safari drop down menu item for that is . . . > File > Save As. This opens a dialog box asking whether to save as Web Archive (images) or Page Source (code). Navigate to the desired folder and hit the Save Button.
