Q: What software is required on my local computer system(s) to support the cameras and upload images? Answer: Two software vendors have implemented the required webcam software changes needed to operate with What-Happened.com. The Microsoft Windows-compatible product is webcampXP. If you are using webcam software from a different supplier, we would be glad to try and work with them to make the necessary, but minor changes to their software to accomodate our services. These changes are not specific to What-Happened.com and can be used in many other applications.
