Well, you also need to look at the source generate (I don't remember every detail of every function).
That would tell you that the html generated looks like this:
`
// if using printLatestImages()
[list]
[*]
(...)
[/list]
So the call would be of course#latest ul li`.
The surrounding div may look unnecessary and mostly it is probably but it gives some possibilities for CSS styling if needed (And you don't want to make your own function using the "get" ones).
