I’m doing a project for school basicly making a website and I did the command
<img src="fruit-salad.jpg">

But when I save, it shows an X in the corner. Can you help?

The path to the image is incorrect…

Instead of using a relative path (ie: fruit-salad.jpg) try using an absolute path (ie: http://www.thedomain.com/images/fruit-salad.jpg)
