How to change EnergyROM "Leo" background and wallpapers

[jamal33]

I really love this Rom but cant seem to find the right way to properly change the default energry background that has the blue wave with my own pic. also when i click on the start menu it has a different background i would also like to change that... I've downloaded theme cab files in the past like COD4 modern warfare but with no luck. I miss windows mobile 6.0 where changing the front interface was as easy as point to the .tsk file or grabing an image form your picture gallery- right clicking and saving as the background.

Can some one hook me up..get me going with a different wallpaper or theme.. I love Dusk Theme but i cant get it to work on this Rom.
Please school me on the proper way to customize the touch pro 2 - manila and sence UI have complicated things for me.

do i drop it in the windows dir or save it to my SD card?

thanks in advance.
