The extension is part of the filename, so you could have all of the
following files in the same directory:
image.jpg
Image.jpg
IMAGE.jpg
IMAGE.JPG
It's just because Unix-based filesystems allow many more characters to
be used as part of the filename, and thus, as upper and lowercase
characters are different characters with different ascii codes, it
treats them as unique.
