Here's the solution for the logo problem.
The easiest and effective way is use RCOmage 1.1.1 to decompress the opening_plugin.rco
Change the logo.png (or the logo you will be replacing) with with an 8-bit png.
>To make an 8-bit png logo, Use 'Save for web' in photoshop and select "png-8" in the drop down box. Choose "perceptual" and "254" colors
>For better quality, use a colored logo with a transparent background. I used a black and white transparent logo and it was awful.
>Images should be lower than 10kb
Replace the logo with the one you made in photoshop and compile it using RCOmage. :D
[Notes]
Using RCOedit in replacing the logo with a png bloats the filesize and that's why the opening_plugin.rco didn't render properly.

Now my next problem would still be implementing the slideshow background... ^^;
I still can't figure this out.
