How do you email a pic to a cell phone?

Is this a smartphone? It's got an email app. Just open that and send an email with an attachment as you would an email to another computer. If it's a basic phone without email, are the phone and computer near each other that you can simply connect using a USB? If so, insert a microSD card, make the usb connection and set the phone to be connected as a USB Mass storage device. This will turn the card into a flashdrive that you can just save the pictures to.

This is how I email a picture from my computer to my phone. I put my email address in the to line for a text message on my phone. Then I send a message like "Hi" to my email from my phone. Get onto my computer, Go to the email, save the address which will have your phone number in it. Then reply to the message with an attachment of the picture you want. If you send yourself an email from your phone, you do not have to guess what your phones email address is.

Ya you do butit also depends on their carrier and if they get pics.
