How to fix my JPEG pictures?

I uploaded some pictures from my iPhone to a flash drive about a month ago… But now if I try to open them with any program, the program states it doesn't support this type of file! They all open my other JPEG files who are older than a month old, so why does this happen and how do I fix it?

Unfortunately, all of your photos are of little boys, which can't be fixed. Please grope on your own time.

Try moving them to the pc then opening them. It might be a faulty flash drive.
