Is there a way of setting a standard name for several pictures with the files being deleted as new ones are uploaded so I can put a 'rotation' of pictures on a web cam web page or am I restricted to either just a single image or using streaming?

Eg: I want a web page showing the last 99 pictures, numbered Picture1.jpg - Picture99.jpg as the counter reaches 99 picture 1 is deleted and replaced by the next one.
