Broken image links even though links are correct and images exist

Question

I recently migrated my site from BlueHost to Siteground. The uploads folder was not migrated properly, so I had to ftp many of the folders manually. Most of the images are showing up properly now, however, some of them are still not showing. For example on this post most of the photos are not there. But there is one that is. When I go into my file manager however, I see that the photo IS THERE.

For example, the first photograph which is broken, links to "https://i0.wp.com/madhouseheaven.com/wp-content/uploads/2015/03/Santo-Antão-021-1024x579.jpg?resize=1024%2C579&ssl=1"

When I look inside the folder, the image is there.

Answer 1

In the end the solution was to delete the files in the month folder (it doesn't work when I delete the entire folder and put it back again for some reason) and add all the individual files back into the folder.
