Then put these pictures on your web site, so if you are talking to a customer on the phone, or sending and email, you can lead them to the page with a picture of whatever you are trying to explain. A picture really is worth a thousand words. A picture can explain things better than I can. Pictures on a web site can make it easier for you to help your customer get what he wants and needs.
I also load these pictures on my iPhone. I can whip it out and with a few pokes and swipes, show someone what I am talking about. Any cell phone with a camera can save pictures and pull them up when needed.
I carry a digital camera in my truck because the camera in the iPhone isn't that great, but the phone camera has helped me on several occasions. I have been able to take a picture of something and email or attach to a text message and send to a contractor or employee. If you have a camera phone, take the time to learn how to do this before you need to. It can save a lot of time and a thousand words.
Oh yes, I have pictures of my grandkids on my phone too, but I try to resist the impulse to show them to my customers (unless they ask).
