It's simply a photo filter applier. Filters should be like instagram filters, not exactly same but as close as it can get.
1. Swf gets an image file (jpeg only) with programatically specified url and a keyword (both not embedded to swf)
2. User chooses one of filters (4 or 5 filters)
3. Swf applies filter to image and sends back to image and keyword to host with post method.
This is a sample; http://pixlr.com/o-matic/
But what we want is much simpler, only 4 or 5 filters. No complicated design at all. Just preview of the image and filters to click at bottom. Just like in the sample.
