rename?

Can someone help me with just a quick re-naming of a file?

 

I edit an image but it always returns the same image before it was edited I guess because its caching the image. I have tried everything with cache and give up.

 

So after editing the image i want to assign it a new name and return that to the view.

 

So it will always be a new file name after each edit.

 

592254896.jpg to rand() + the original extension.

 

Thanks,

 

Dave
