Images Not Displaying

When uploading images through the theme such as the logo or images within listing that works fine but when trying to add an image to a page or in a text widgit the image is not displayed. I've tried uploading through wordpress and also uploaded directly through ftp with the same results

http://www.stokebusinesslistings.com/test-page/

If you look at the code the image tag is shown and if you visit the path of the image its there on the server http://www.stokebusinesslistings.com/wp-content/uploads/2013/04/advert_gold.png
just not displaying within the page.

Can you help please.

Regards
Jamie

 

Sorry I've solved the problem, seems using the word 'advert' in the image name is not a good idea when using Firefox with an add blocker.
