File error when viewing pics

Your pictures appear to have been corrupted.
Here is what you can try:
copy the files from your card directly to the computer HD. Then look at the files with your computer system browser, and choose the full view, or in Windows it would be VIEW/ List or details . If the names are missing any letters, then simply do this:
Make a copy of the original file and rename it to something like:

I_G123B,jg (original renamed file...note that I added the B so the name is not the same as the original) to IMG123.jpg . Once the file is renamed to what may have been originally, you will be able to view the picture again.
Some times the corrupted name may be even more confusing. The main thing to remember is to make sure you have a .jpg or .JPG at the end so that the computer system will recognize the file format and be able to read the file. The way you name what is before the period ( .jpg) is not that important, but should reflect the original file for your own information.
This file corruption is more common than one may think. I have seen it on Nikons, Sonys, Canons.
And others.
