You might need to be specific regarding the model of your handphone.
You can use a USB cable, a memory card, bluetooth or infrared. Assuming you don't have those, try contacting Verizon and ask for their opinion.
My service provider provides an alternative for me to transmit pictures from my handphone via WAP. I can log into my service provider's website and uploads images from my PC to their server so that subsequently, the pictures could be transmitted via MMS. Maybe Verizon has similar concept?
