Design modification in Wordpress extension -- 2

I am using Wordpress + 3rd party extension to allow user upload an image on top of a template. [login to view URL] I would like to make a design change and replace the current zoom in / out and rotation of the uploaded image to a slider. I have also created a draft as an example. So the change is to make 2 sliders to control the zoom and rotation of an image instead of the square control around the image. Should be pretty simple as the function is already there. Who can do this quickly, asap?
