file upload name
have a database with upload image fields for each person in it.
All works well on the initial upload of 1,2,3,4,5 .jpg etc
However if I register as a second user and then upload a different set of images but with the same name ie 1,2,3,4,5.jpg it over writes the original files.
I selected server assigned name but how do I make the name unique ie the server renames the file to 1_1 or similar?
