As you may have noticed, images in Markdown are very similar to links. The difference is that:
- the square brackets must be prefixed with an exclamation mark and
- inside they may have some alternative text. A description of the image, which is displayed if the image can't be loaded.
Here's a quiz about markdown images.
Select the valid images:
-
[Google logo](https://www.google.ru/logo.png)
-
![](https://www.google.ru/logo.png)
Images must be prefixed with an exclamation mark. The alternative text and a title are optional.
What is true about the following line: ![Funny cat](http://cats.ru/funny.png "Share this")
- if the url is 404, "Funny cat" will be displayed
- exclamation mark can be omitted in this case
- if the url is 404, "Share this" will be displayed
- on mouse over the image "Share this" will be displayed
Similarly to links, images can have 3 parts: the alternative text, the url and a title. An exclamation mark is nesessary.
