Filereference vs forced download php

Hi… sorry but posted it also on actionscript 1.0/2.0
a time ago was playing around with filereference because i wanted to make photogallery with a option to download the pictures. I took me a couple hours to figure it out and get it working. see here problem is/was that people cant change the name of the file because i wont be recognized anymore. you good put the extension behind the name, but not everybody knows that. So lately i was searching for a solution. Why isn’t it possible to put an extension while saving with filereference. I couldnt find the answer. But i stumbled into a small solution. force it with php. this will keep the file extension. a pity is that i lost my download bar and function with this. check it out [URL=“”]here if someone wants the code mail me. toubmor
