@Greeps. Thanks for posting. To be able to assist you fully, please post the link to the webpage with the listing, and let me know what OS your server is on, and the PHP version. However, based on what you have posted so far, you seem to have “imagesstoriesPDF”. However, it is worth noting that you should use forward slashes, and also note that the directory names are case sensitive. So, it should be “images/stories/PDF”
I am not sure about what type of image you are trying to view. You may need to provide a link and more detail such as the image file type. I should be able to assist you further with more info from you.
