Bomber iNav issues

[vegasj]

Hey all, noobie here to Jailbreaking.

I just got setup with Bomber iNav theme for Winterboard & I have no lock screen picture showing, want to:

1. change my charging battery pictures to fireepainter by Jesse,
2. change my unlock slider,
3. possibly add custom lock screen things like calendar & a different clock
4. also change the battery in my status bar.

can these be done even though I'm on Bomber iNav through OpenSSH? I've already connected with WINSCP and found my Bomberinavv2 folder... the lockbackground.png is there, but it just doesn't show when locked. Can I drop the battery png files in there somewhere?

I'm sure renaming png files and putting them in the correct folder would work but this is the first time I've viewed the root of my iPhone 3G.

thanks in advance!
