I'm developing a system that will store alot of images in a single folder. I need the folder to be secure, so users may not view the images in the folder. I cannot use somthing like .htaccess files, as they are not compatible with every server (this will be distributed, so it needs to be universal)
My idea is this: The images in the folder are going to receive random names like "023712ygH.jpg" or "nch9823dg.jpg". So people can't look in the folder, there will be a blank index.htm file inside. I just want to know: Is this a very secure method? And is there any way people can still look inside the folder/find the file names? Is there any image re-direct methods that work on every server?
