How To: Displayed image file name different than actual filename on server

I would like to display an image but have the file name different than the actual file name on the server.

ex) The user开发者_JS百科 would see <img src="/img/photos/Awesome_Picture_By_John.jpg"> by looking at the source code

but the actual file name would be /img/photos/12b7dch2.jpg

any help is appreciated. Thx

It can be done pretty easily. I think you could do something like this with mod_rewrite, turn the existing

/img/photos/Awesome_Picture_By_John.jpg

Into something like

/img.php?id=Awesome_Picture_By_John

and have img.php pull the real filename out of the database.

Here is a good mod_rewrite tutorial to get you started.
