Memory Card Full and No Image
You probably shot the photos in raw image form and your image uploader does not except raw. There are a lot of free image converters. Since most computers are picture bridge, people just connect the camera and forget to upload the software that came with the camera which has a program on it for uploading raw.
If you lost the software that came with your camera you can usually find it on the camera manufacturers page. Or you can upload one of the free image converters that does raw. Also you might need to upload a raw viewer for my pictures, it is a free add on also.
