best way to upload and rename an image

lol I really didn't mean to set off a fire here.

The difference is that if I upload an image of the same name during my process, it appends a number ( 1 as the example ) to the end of the file name, so image.jpg uploaded again would produce image1.jpg on the server. What I did not realize that upon doing that, it would also provide me with image1.jpg as the name as the file instead of just image.jpg which is the name of the local file that I am uploading. The major concern with this problem is that I didn't want the admin to overwrite product images accidentally.

And yes, if this were files being uploaded via non admins I would do a lot more to ensure that the files were not executable via url. And I do appreciate the PDF linked.
