best way to upload and rename an image

I don't like putting images into BLOB fields of databases. The main reason is you will often have data limitations within hosting providers that would become tiresome through the life a site. The second reason is out of ignorance on my own part. I have not tested or researched testing on how images serverd from db's compare to images being served as files from your site. It has been my practice in the past to reduce the db load and not increase it. But again my preference could be greatly influenced by my admitted ignorance.
