I have a Rebel XT and am using a USB cable that plugs into the camera to upload pics to my computer. I'm noticing it takes 10+ minutes to transfer 100 or so pictures. I get the initial popup asking if I want to select the pics or just download them but after that nothing else happens. Maybe 10 minutes later the Picture Viewer will pop up out of nowhere. Is there a faster way to transfer my pictures to my computer?
