I meant that almost no picture organizer in linux is fast. Not even *picture showing* programs. digiKam can flash through my big pictures with me looking 0.5 sec on each before going to the next. I haven't found any GTK/Gnome image viewer that is so quick.
Not even feh, qiv et.al. can beat digiKam's speed. I love it. I don't want to wait for the program when looking through pictures.
