Update markdown.md

i change how to iclude img in markdown because in the way was made doesn't work

[syntax-tm]

Purpose

This example is a single reference-style image. The [img] at the end of the line is the link label. That link label refers to a link reference definition that can be found on the second line.

![Image alt text][img]
[img]: http://foo.com/img.jpg

Proposed Changes

With your changes the first line is no longer valid because the link label img no longer has a matching reference definition.

![Image alt text][img]

The second line is just an inline image whose alt text will be set to img.

![img](https://foo.com/img.jpg)

So, this example of a reference-style link is now an invalid link since no matching definition exists and the second line is just a duplicate example of inline syntax.

The Fix

A reference link is comprised of the link text and the link label. That link label references a link reference definition located "elsewhere in the document."

![Image alt text][img]

[img]: http://foo.com/img.jpg

Basically, you just need to add at least one empty line between the image and the link definition.
