Moving my blog images to Amazon

We are trying to a few things on our site.
1. we want to move all the images off our site and host them on Amazon S3 storage
We have moved the first folder called "images" on our Siteground server and made a new called "hhhimages" on Amazon

1. We need to change all the links in all of our content to change any link of any image in our blogs to the new Amazon links.
we dont want to have the original file on our server we want to delete it after.

I tried replacing the link in my Easyblog posts to images it found them in the blog intro and content tables but not in the code below.

<a class="eb-post-image-cover eb-image-popup-button" href="//http://www.mysite.com/images/easyblog_articles/2537/Why-Homeschooling-work_20161221-220337_1.png"; title="Why Homeschooling Works" target="_blank" style="

Easyblog is creating new resized images with new names
As a result I cant replace my images from my server to amazon?

How do I change these image links and paths so I can move my images to Amazon?
