Moved blog location, uploaded file URls won’t update

Previously, my blog (https://blog.mildlyhotpeppers.com) was stored in a folder named “blog” inside the public_html folder. When I uploaded images, the registered location of the images were https://www.mildlyhotpeppers.com/blog/wp-content/uploads/ …

Now, however, I moved my blog to the root, meaning it can be found at https://www.mildlyhotpeppers.com/. The images, however, will not show up. When I go to manage and then uploads, I see that the image URLs are still the same as before moving. It is supposed to be updated, though, to https://www.mildlyhotpeppers.com/wp-content/uploads/…

I changed the wordpress address in the options menu already, and everything else works fine except this. Can anyone tell me how I can change the URLs of the uploaded files (manually or using a script)?
