So I have found a solution to this problem.
The images are in fact still there, and all you need to do to get them back is edit your post in any way. If you have a post with pictures made before the URL change just make an edit, doesn’t matter how small you can literally just add an extra space and the images will be back
So this solution only works on yourself meaning everyone (especially artists) who made posts with pictures in them have to manually edit their posts for the images to show again
