In Markua, you add an image to a book like this:

In this example, the filename of the image is cake.jpg, and the caption is A Piece of Cake.

If you don't want a caption, you can just leave the space between the square brackets [ ] empty, like this:

...but please remember, you always need to include the square brackets!

Also in Markua, you can link words or sentences to a web page, like this:

In this example, the web page address is https://unsplash.com/photos/I48gnI1Qs5o, and the words that will be formatted as a clickable link are A Piece of Cake.

Normally, wouldn't make a whole sentence into a link, but you would instead to something like this:

Now, this next bit is a bit mind-bending at first, but basically, to make an image a link, you put the image syntax in the first example above, inside the link syntax in the second example above, like this:

Here is an image showing the part of the line that is the image syntax:

If we blur out the image syntax, you can see how it is now inside the link syntax:

Here's an example you can copy and paste, to try it in your own manuscript:

OK, that's it!
