You would use one of the theme properties used by roAppManager, please see:
http://sdkdocs.roku.com/display/sdkdoc/roAppManagerGenerally speaking:
sub main()
InitTheme()
Poster=createobject("roPosterScreen")
Poster.setcontentlist([{},{},{}])
poster.show()
while true
print "hi, I'm running"
end while
end sub
function initTheme()
appman=createobject("roAppManager")
theme=createobject("roAssociativeArray")
theme.OverhangSliceHD="pkg:/images/overhang_hd.jpg"
theme.OverhangSliceSD="pkg:/images/overhang_sd.jpg"
appman.settheme(theme)
end function
