Customize jQuery Slider to Preload Images

We purchased a jQuery slider plugin for Wordpress, "Royal Slider". It currently has the option to preload images but it slides to the next image even though its not yet loaded. What we want to do is make sure that the next image is done loading and then slide to it but never slide to an image that is half loaded. You can preview what the slider is currently doing here - [login to view URL] (It continues to the next image even if its not loaded) The images in the slider are very large, about 800kb to 1.5mb in size. I did find a jquery plugin to fix this I just don't know how to implement it into our existing Wordpress plugin. [login to view URL] (This is a unique slideshow script that, unlike most other, will intelligently preload its images one at a time, while the preceding image is being shown. The script will actually "wait" until the next image is successfully preloaded before continuing, trying again if not.) We need this done as soon as possible as we have a deadline on this for tomorrow. Please only bid if you can begin work immediately.
