Unless it is disabled, Windows has the autoplay feature which will display a window asking what to do when new media is installed; does this actually happen when you insert the cameras memory card? FAt that point the drive should have been assigned a drive letter and you can simply select open in windows explorer folders from that autoplay menu. Then in Windows Explorer set the view to "medium/large/extra-large icons" and the items should be displayed as thumbnails. At that point you drop and drag them to any folder on your harddrive or you can
add the "copy to/move to" options to your context menu (the right-click menu) if you prefer that to drag/drop. Finally use windows explorer's rename function to give the file a name more meaningful.
BTW, technically that is not termed "uploading". Uploading would be sending the files across the internet to a website; what you are doing is a file transfer from one drive (the camera's memory card) to another drive (the computer's harddrive).
