Okay if nothing has changed and everything is 777 and you do not have an htaccess file that is blocking the picture display then please explain why you can not type in your browser this and get a picture.

Your issue has to do with permissions on the data directory or some change on your server related to blocking the display of the images and not photopost itself. Your telling Photopost the right url and path to the images correct? If so then there is something else here blocking the display of those images. If they exist where your telling me you should be able to display an image in the browser like I noted with a direct link to it as I showed and on your site it is not allowing this
