Angular 2 - Check if image url is valid or broken
<p>I am fetching a large number of image URLs from an API and display them in a angular 2 web application. Some of the URLs are broken and i want to replace them with a default picture that is stored locally on my webserver. Does anyone have a suggestion how to test the urls and in the case of status code 404 replace the broken image?</p>

<p>Thanks!</p>
