Ok, but how do you know in advance how much time will be needed to show the 
image? Remember the KPart can get input from a large number of different 
IOSlaves, and also the image size can be much different.

If the speed impression is important the viewer could wait until the image 
has loaded, or, say, half a second has passed, and then update the view 
every second or such. This way you could go pretty fast for fast ioslaves 
or small images, and still show progress to the user.

To return to the topic, I would go for a simple one-image part, and another 
separate image list management part. These could be combined in a two pane 
part in konqueror, for simple tasks, or in a more specialized application 
for organizing tasks and maybe simple editing.   

GwenView interface seems ok from my point of view (I normally use it as a 
Konqueror view, however, so maybe I am a bit off the mark).
