jpg viewer with quick brightness adjust

[stan]

Hi,

Since Fedora 9 I haven't found kuickshow in the repositories.  I presume it grew old and died.  I've tried lots of other 
viewers, and many were fine, but they all lacked a feature that kuickshow had.  There was a brightness adjust using 
keyboard shortcuts.  Other viewers allow the adjustment of brightness, but it requires clicking through menus, and so it 
isn't as easy to use.

Can anyone suggest a viewer that has that capability?

Thanks.
