I've searched through the forums and not been able to find a fix for my issue.
I am using WP 3.5.1 and the free Classic Theme from Vandelay Designs and my site is at http://www.ianhornephotography.com
I have just started creating the site and came across this issue almost immediately. I have added a .jpg image to the media library, the size is 1024 x 1017. I have up gone into the Home page and added this image and it shows up there. If I Preview the page I just get an image placeholder where the image should be. The url for the image itself works - http://www.ianhornephotography.com/wp-content/uploads/2013/02/Ian1.jpg (just a test picture :-)) as does the view attachment page.
I'm stumped. Any help would be greatly appreciated.
