AJAX GUI for picture gallery

Looking for an expert in AJAX frameworks (ExtJS, adobe Spry, Dojo, YahooUI etc.) to create an AJAX-based image gallery GUI component. This should be a relatively simple component for AJAX experts who are good at AJAX-based UI. The AJAX component will be used to provide a mechanism for our users to upload image files and select images from the image gallery. You do not need to work on the backend. However you will need to document clearly the call interface to the PHP backend (to be defined and coded by us) via JSON, HTTP parameters, or the like. Further design / requirements will be given on request. ** AJAX Experts only please. ** If qualified and interested, send me a message showing some of the related work you've done.
