Welcome to the community and feel free to make yourself at home and one way to transfer your pics is hook your X up to your computer in usb storage mode and also hook up the TB to the computer at the same time. Once you have gone to My Computer and opened up each phone's folder just go to DCIM and cut and paste the pics to the TB picture folder. Let us know if you have trouble Doing this and glad you joined us.
Spaz also gave some good info too hope it all can make sense.
Have you checked to see if it is in USB stoage mode? This option should be available when you pull the pulldown menu open. Just click on USB connection in the pulldown menu and make sure it is in USB mass storage mode
Well I'm glad spaz is helping u get those drivers. Spaz def knows the ins ands out of moto and android. Also its no problem I'm here to help and hopefully we will get u up and running. Also might wanna check menu>settings>applications>development>check "usb debugging" just make sure usb debugging is checked so it is ON. I hope some of this can help
