Deleted Image giving a 301

I have images that were deleted from the site (the page and the media library) but are still being requested which can be seen in the network tab. They are redirected and take a huge amount of time making the page significantly slower. I don’t know how images that no longer exist on the page and the media library can still be requested. I tried adding images with the same name but they are still redirected (probably because I set all 404’s to redirect to the homepage). attached is an image with the images causing the problem.
