Javascript to display webcam JPGs

This should be very simple for experienced Javascript programmers. I have a website which needs to display webcam pictures. I need a javascript to load the JPG and do the displaying (to avoid server caching problem) and refresh regularly. There is a special requirement. It will receive two file paths and have two radio buttons to let the user pick which one to view. So the function contain these input 1. two file paths (the second one optional) to JPG files. 2. refresh interval. The view will be 1. The picture 2. If two paths are given, display two radio buttons ("Pic 1, Pic 2"). Default to "Pic 1" and display the first jpg. 3. It refreshes automatically at the interval. 4. If the JPG file is being uploaded so it is incomplete, the script should wait for the complete JPG file. 5. When the user click on the radio button, it should load the other picture and load it right away. ## Deliverables 1) Complete and fully-functional working program(s) in executable form as well as complete source code of all work done. 2) Deliverables must be in ready-to-run condition, as follows (depending on the nature of the deliverables): a) For web sites or other server-side deliverables intended to only ever exist in one place in the Buyer's environment--Deliverables must be installed by the Seller in ready-to-run condition in the Buyer's environment. b) For all others including desktop software or software the buyer intends to distribute: A software installation package that will install the software in ready-to-run condition on the platform(s) specified in this bid request. 3) All deliverables will be considered "work made for hire" under U.S. Copyright law.
