When you click on the browse buttons a pop up menu will come up with a list of locations to upload the images from. Select the camera (removable or external drive), then select the folder and files.
Dont have removable or external drive listed.
Doesn't 'see' the camera. You may have to install the camera's driver on that PC, if it will let you. The computers administrative properties may not let you install outside software without authorization.
