Needs more test cases

[Lwdthe1]

Thanks for this module. I just noticed some failed tests

The url example.png is not an image, but is-image says it is an image

The url example.png?size=1&color=b is an image, but is-image says that it is not an image, and I think its because of the query string

From the top of the readme:

It just checks the extension. Use image-type if you want to check the actual file.

Ah, thanks for pointing that out.
