Clone didn't change url of pictures inside posts.

I used Cloner to duplicate a site, but when it came through, the pictures inside pages/posts still had the url of the picture from the original site.

For example:

<img src="http://www.ORIGINALsite.com/image1.jpg">

instead of

<img src="http://www.NEWsite.com/image1.jpg">

Where is the setting to make it change all the urls to the NEWsite?

I used "Cloner". Should I have used "MultiSite Content Copier"?

Thank you.
