|OK but where they are actually filed are their file extensions .jpg? Look at some other pictures you have saved because almost always they will be jpg. If the extensions are not showing then follow what I suggested in #4.|
What I'm trying to find out is whether there is some difference between these stills and any other photo's you have, also whether your other photo's still open normally. The place to check this is in your Pictures folder.
Note that in both cases I am talking about the "actual folder" they are stored in - not some photo gallery which is just reflects the contents of folders and may or may not show file extensions.
If we can get the above sorted we could be well on the say to solving this issue.
Always pop back and let us know the outcome - thanks
