For every image uploaded there-after your odds get worse and worse for a conflict happening. If you really must use this method please at least do a file_exists() check first to make sure your random number hasn't been used. WS> Anyway if same name is created what's the best way to check that? Depends how you are storing it - if it's in a database then check to see if that ID is used. If just a plain file, use file_exists. WS> I was thinking of putting the image name field in DB as a unique WS> field. That would do it? Right? Yes it would ensure the filename was unique, but unless you actually need it in a database it's probably not worth the effort. Just check for the actual file itself.
