Pretty much agree on all but the title. The title is useful as an action tool. When you hover over an image with a title, the title text will appear near your mouse. When an image is linked, it can be used to describe the expected action. "Click to Enlarge" or "Click to read more. " or sometimes even things like "Photo Credit: Bob Cameraman" It's redundant as the same as the alt. People who can "see" the image don't need it described and the people who can't see it will see or hear the alt text anyway. The title can drive the experience or expand the experience without distracting from the main path to goal.
