Image viewer for gnome (ACDSee clone?)

[Cedric Chausson <cchauss mail club-internet fr>]

Hello,

I'm looking for a clone of ACDSee for Gnome. I'm especially looking for
the feature where you can look at each picture at real size and view the
next one in directory just by pressing a key or rolling the wheel mice
instead of having to close the current file and open a new one.

Any candidates out there ?
