Slideshow Pro Module Help

Hello,

I am attempting to create a slideshow pro module for Gallery 2. This is my first module attempt. The Slideshow Pro swf file needs to load an xml file that I am dynamically creating in the module. I need to know the 'best practices' for how to create a temp file and delete it after the .swf has loaded it. I was creating temp files in my data directory, the problem is that the .swf file can't access that directory through a standard http url.

Thanks in advance for any suggestions.

Dave
