I am having the problem shown on the uploaded picture with about half of the 500 photos I took on my new Canon T3i. This was the first time I have tried to download the pictures and have no idea what the problem is. The same thing happened when I tried downloading to my iPad and computer using both iPhoto and the EOS utility software. If I had to guess what the problem is it would be the memory card, but I am new to this kind of stuff. Any help would be greatly appreciated. Also, the whole image is shown in the preview prior to download, and on the camera.
