Cannot upload image to my Custom Pages Follow

Hi, I'm trying to upload images for my ReSharper plugin Custom Pages and they're uploaded blank. It worked about week ago. My plugin is File Layout Extensions. I've tried to reupload the images, but they're still blank. Even the image links that use them, behave like the images don't exist. Am I doing something wrong or is it not working at this moment?

Thanks for you reply,
