Applet flash modification

Hello I have the sources of this program in action script. I want to modify. First I want a browser button that lets browse the hard drive and loading an image of the size [login to view URL] (good resolution pictures sources only) ! Unlike now unfortunately I can only work on the image of the ugly boxer. I want a zoom and an opportunity to move into the working window with buttons for example lifts button or drag and drop. Secondly I want to export the work (the triangle picture) with a save button and output in high definition i have no interest in low resolution. Thank you
