The uploaded images have quit showing up in 2.9. There are also no more thumbnails when you go to review them. But if you go into edit, you can see the files and they are all still there.
Also, if you input the full URL to the file, it comes up as "Oops! That page wasn't found!"
Sure there is a simple answer to this, but darned if I know what is going on at the moment...LOL
