If you do not want to spoil the src attributes on your website, you can consider changing the configuration directives.
You can move it by editing the DocumentRoot parameter in C:\xampp\apache\conf\httpd.conf .
Currently, it should be installed as:
 C:/xampp/htdocs 
Change it to:
 C:/xampp/htdocs/exampleSite 
and your relative link as <img src="/images/sidenav/analysis-2.gif" /> should work fine.
Note:
- Remember to restart the XAMPP server after making the changes.
 - After these changes, the lead 
/ will always be directed to the exampleSite folder. If you decide to change the root later, repeat the process for the root folder of your choice.
