Steps to reproduce:

1. Activate Local Staging
2. Add Blogs portlet to page
3. Add a blog entry
4. Add a cover image via Item Selector > Upload Image > Select File > Add
5. Publish
6. Publish to Live
7. In Live Site, go to Site > Content > Blogs > Images

Expected Result: Similar to when in Staging, the image displays in the Blogs repo, in the live site.

Actual Result: The image does not display in the Blogs repo, in the live site.
This issue is also reproducible with any image added to the Blogs repository (ie. Small Image, inline image).
However, adding a blogs entry with an image before publishing to live will display the images in the Blogs repository, in the live site.
