How to change security lock photo on Handcent?

[mauiblue]

I setup the security lock for Handcent but for the life of me I can't figure out how to change the photo/wallpaper that's on the security screen of Handcent. Anyone out there knows how to do this. TIA!

Update 09 Sept 10: Figured it out via the Sense wallpaper. Thought it was an option on Handcent.
