I'm working on a website built in Symfony, where the image links are stored in a database (the page I'm working on is database driven) and the actual images are in an images folder. Several images have been added to the page recently, but are not showing up on some computers (even when I go to the image directly, I'm getting a 404 error). I've tried deleting the cache folder, and I've checked the naming of the images to make sure they're consistent with the images on the page that are working. Does anyone know what could be preventing the images from being displayed correctly?
