I suspect the path is not correct. As mentioned by user7412219, Ubuntu and Windows deal with path differently. Try to put the image in the same folder as your Notebook and use:

![alt text](Isolated.png "Title")

On windows the desktop should be at: C:\Users\jzhang\Desktop.

The following works with a relative path to an image into a subfolder next to the document:

![image info](./pictures/image.png)

Solution for Unix-like operating system.

1. Create a directory named like Images and put all the images that will be rendered by the Markdown.

2. For example, put example.png into Images.

3. To load example.png that was located under the Images directory before.

![title](Images/example.png)

Note : Images directory must be located under the same directory of your markdown text file which has .md extension.

To add an image in markdown file the .md file and the image should be in the same directory. As in my case my .md file was in doc folder so i also moved the image into the same folder. After that write the following syntax in .md file

![alt text](filename)

like ![Car Image](car.png)

This has worked for me.

The best solution is to provide a path relative to the folder where the md document is located.

Probably a browser is in trouble when it tries to resolve the absolute path of a local file. That can be solved by accessing the file trough a webserver, but even in that situation, the image path has to be right.

Having a folder at the same level of the document, containing all the images, is the cleanest and safest solution. It will load on GitHub, local, local webserver.

images_folder/img.jpg  < works


/images_folder/img.jpg  < this will work on webserver's only (please read the note!)

Using the absolute path, the image will be accessible only with a url like this: http://hostname.doesntmatter/image_folder/img.jpg

if image has bracket it won't display

![alt text](Isolated(1).png)

rename the image and remove brackets

![alt text](Isolated-1.png)

Update: if you have spaces in the file path, you should consider renaming it too or if you use JavaScript you can encode it using

encodeURIComponent(imagePath)

Also, always try to save images and files alike with lowercase, please develop that habit, just my personal view though

Adding a local image worked for me by like so: ![alt text](file://IMG_20181123_115829.jpg)

Without the file:// prefix it did not work (Win10, Notepad++ with MarkdownViewer++ addon)

Edit: I found out it also works with html tags, and that is way better: <img src="file://IMG_20181123_115829.jpg" alt="alt text" width="200"/>

Edit2: In Atom editor it only works without the file:// prefix. What a mess.

Depending on your tool - you can also inject HTML into markdown.

<img src="./img/Isolated.png">

This assumes your folder structure is:

 ├── img
     └── Isolated.jpg
 ├── README.md

Just add the relative image file route from the markdown file

![localImage](./client/src/assets/12.png)

This worked for me in ubuntu:

![Image](/home/gps/Pictures/test.png "a title")

Markdown file is in:

/home/gps/Documents/Markdown/

Image file is in:

/home/gps/Pictures/

There are a few formats that we can choose from as the official website shows. One of it, if you put a

![alt text](Image.jpg "Title")

The path can be relative an absolute too (the example use relative). The above assume Image.jpg is in the same folder as the markdown file. Relative paths are useful for repositories, when others clone the project into a different folder.

The alt text will be shown if the picture cannot be drawn on screen.
The Title is optional and it will be the tooltip (mouse hover over). Several screen readers rely on those values, be kind and write meaningful text.

If you use spaces in filenames, like Arthur Dent.jpg then you need to wrap the path in < > as follows:

![Arthur's profile picture](<Arthur Dent.jpg> "Title")

Here's an example of referencing an image from a neighboring folder

root
├── Documentation
|   └── Readme.md
└── Resources
    └── Arthur.jpg

Then, in Readme.md (../ one directory up, Resources/ within Resources folder, Arthur.jpg this image):

![alt text](../Resources/Arthur.jpg "Title")

Edited:

Working for me ( for local image )

![system schema](doc/systemDiagram.jpg)

 tree
 ├── doc
     └── jobsSystemSchema.jpg
 ├── README.md

markdown file README.md is at the same level as doc directory.

In your case ,your markdown file should be at the same level as the directory files.

Working for me (absolute url with raw path)

![system schema](https://server/group/jobs/raw/master/doc/systemDiagram.jpg)

NOT working for me (url with blob path)

![system schema](https://server/group/jobs/blob/master/doc/systemDiagram.jpg)

In Jupyter Notebook Markdown, you can use

<img src="RelPathofFolder/File" style="width:800px;height:300px;">

You may find following the syntax similar to reference links in markdown handy, especially when you have a text with many displays of the same image:

![optional text description of the image][number]

[number]: URL

For example:

![][1]

![This is an optional description][2]

To my knowledge, for VSCode on Linux, the local image can be normally displayed only when you put the image into the same folder as your .md post file.
i.e. only ![](image.jpg) or ![](./image.jpg) will work.
Even the absolute path like ![](/home/bala/image.jpg)also doesn't work.

Another possibility for not displayed local image is unintentional indent of the image reference - spaces before ![alt text](file).

This makes it 'code block' instead of 'image inclusion'. Just remove the leading spaces.

Displaying local images in .md file (VSCode reader extension)

In my case, I tried a lot of solutions to display an image in my vscode .md reader, but none of them works. But it appears that it only works when you specify the full path to the image from the root for example: ![My image](/c:/fullpath/to/image.png).
The trick is you need to specify / before the letter c of your drive

just copy the image and then paste it, you will get the output

![image.png](attachment:image.png)

For me working fine with gitlab when I have specified URL to image started from ./

Please double-check that you don't have the space between [] and ()

![img] (URL)
      ^

Sometimes very confusing.

I recently needed to add images to a README.md file in Github. The image can be reference via the repository root path.

Note: I used a standard image tag because the markdown syntax doesn't play well with tables.

Github repository structure:

repo/
  - src/
    - branding/
      - README.md
      - doc-assets/
        - MAB-8942-Before.png
      

In the README.md file:

<img src="/src/branding/doc-assets/MAB-8942-Before.png" alt="Before image">

Either put the image in the same folder as the markdown file or use a relative path to the image.

I've had problems with inserting images in R Markdown. If I do the entire URL: C:/Users/Me/Desktop/Project/images/image.png it tends to work. Otherwise, I have to put the markdown in either the same directory as the image or in an ancestor directory to it. It appears that the declared knitting directory is ignored when referencing images.
