I have a Gateway desktop running Windows 7 Home Premium.  I am trying to download some photos from my cellular phone to my computer.  My computer does not recognize when I connect my AT&T Z221 phone to the USB port on the front of the computer; the computer thinks my phone is a modem.  I have downloaded the correct driver from Mediafire.com, but it does not help.  Two questions: where do I store the driver so that Windows Live Photo Gallery can find it and use it, and then how do I convince my computer to recognize the phone and find the photos?  Thank you.
