Modification to PHP / Flash Post Image Script for Zazzle API

I have had some flash actionscript and php made to push an image to zazzle through API Basically its an avatar flash avatar maker which allows people to press a button and the design to be sent through API, encoded and then ordered on a teeshirt The code I had made does work but its not performing just right. Apparently it needs to create and save the image on the server with a random unique file name each time. Then it pushes each unique file through the API url with the encoding.. the code needs modifying so it produces a unique file each time, then its pushed through the api (url below) At the minute its not creating a separate image just a random number each time and this seems to be causing a problem The url parameter name is coverimage This is the correct api url: [login to view URL] Also its working as a pop up which is a problem too Basically the project is complete but it just needs a few fine tweaks. Anyone who has worked with zazzle before would be great. I could do with a better button adding to the flash too Its a project which I posted to have done a few weeks back but it just needs fine tweaking
