As above. It's strange as it only started happening recently when the upgrade to 3.8 happen.
If I add a brand new photo to the media library, it'll be as follows
http://awesomescreenshot.com/07924h0vef --> Just before added any photo
1) Photo added. Thumbnail can be seen in the media library
2) Then I click to add that photo unto the post. It shows a broken image :o
3) But if I click on the broken image, and wait for 2 seconds, the image shows up! :o
And it appears as normal!! :o
And it happens for every single photo I'm uploading after 3.8's update.
