URL Rewrite IIS and Wordpress - wordpress

Question

I have this following web.conf
<?xml version="1.0" encoding="UTF-8"?>
<configuration>
<system.webServer>
<rewrite>
<rules>
<rule name="wordpress" patternSyntax="Wildcard">
<match url="*" />
<conditions>
<add input="{REQUEST_FILENAME}" matchType="IsFile" negate="true" />
<add input="{REQUEST_FILENAME}" matchType="IsDirectory" negate="true" />
</conditions>
<action type="Rewrite" url="index.php" />
</rule>
</rules>
</rewrite>
<defaultDocument>
<files>
<clear />
<add value="index.php" />
<add value="Default.htm" />
<add value="Default.asp" />
<add value="index.htm" />
<add value="index.html" />
<add value="iisstart.htm" />
<add value="default.aspx" />
</files>
</defaultDocument>
</system.webServer>
</configuration>
The wordpress site works, however some images I get the following error if I view an image example http://domain/wp-content/uploads/2018/06/home-slide-5.jpg
HTTP Error 500.50 - URL Rewrite Module Error.
The page cannot be displayed because an internal server error has occurred.

I have added the following to the rules now it seems to work
<rule name="Imported Rule 1" stopProcessing="true">
<match url="^index\.php$" ignoreCase="false"/>
<action type="None"/>
</rule>
<rule name="Redirect Image to HTTP" stopProcessing="true">
<match url=".*\.(gif|jpg|jpeg|png|css|js)$" ignoreCase="true"/>
<action type="Rewrite" url="{R:0}"/>
</rule>
<rule name="Imported Rule 2" stopProcessing="true">
<match url="." ignoreCase="false"/>
<conditions>
<add input="{REQUEST_FILENAME}" matchType="IsFile" ignoreCase="false" negate="true"/>
<add input="{REQUEST_FILENAME}" matchType="IsDirectory" ignoreCase="false" negate="true"/>
</conditions>
<action type="Rewrite" url="/index.php"/>
</rule>
