The image displays correctly for me. Its possible the owners of the website fixed the problem–try holding down shift while reloading the page to clear the saved copy on your computer.

The image is hosted on: https://dl.dropboxusercontent.com/u/9318060/Sky-text.jpg

Can you access it directly from that link?

If you can access it directly but not in the page, can you think of any reason that "third party images" might be blocked?

If you can't access it using the direct URL either, could you check the site's image permission using the Page Info dialog? You can call that up using one of these:

• right-click the page and choose View Page Info > Permissions
• (menu bar) Tools > Page Info > Permissions
• click the padlock or globe in the address bar > More Information > Permissions

Scroll down to Load Images and make sure the effective permission is Allow (either it is set to Allow, or it is set to Use default and you can see that Allow is selected even though it is grayed out).

If images are allowed, hmm, can you think of any reason that the site might be blocked?

Note: The image permission should be checked while on the dl.dropboxusercontent.com URL.
