photomontage app

for vamapaull I need a AS3 photomontage app that takes as inputs 2 images: a backdrop and a image; the backdrop is fixed, semitransparent. The image is movable and resizeable with a free-transform like (with handles on the corners for resizing and anchors for moving). Also, I need two panels/tabs that should pop up when clicked: 'add text' and 'fx'. Each of them is configurable with a XML parameter for a list of fonts and effects, respectively. This thumbnails should only be loaded when the tabs are clicked and not before, to save bandwith. The text tab should have a textfield, an alignment option, color, and font list. The fx tab only shows the different thumbnails. When the user clicks 'Save!', the app navigates to another URL with parameters for the position and scale of the image.
