Google has recently added a Street View capability to their Maps. Right now they only have a few cities, but I hope they'll be adding more. I've located some of the phone booths that I'm aware of and put links to them below:
W. 101st St. at West End Ave. in New York, NY.
W. 100th St. at West End Ave. in New York, NY.
W. 90th St. at West End Ave. in New York, NY.
W. 66th St. at West End Ave. in New York, NY.
If you're aware of any other phonebooths visible on Google Street Level Maps, please send us an email at webmaster@thephonebooth.com or using the contact us form.
Here are some other shots of payphones in San Francisco. They're not in booths, but they're still interesting to see. The images of San Francisco are much clearer than those of New York.
Market St. at 6th St. at Taylor St. at Golden Gate Ave. in San Francisco, CA.
792 Market St., 992 Market St., 938 Market St. or 874 Market St. in San Francisco, CA.
