Problem viewing images with Plucker & Sunrise

[Maya]

Hi,
Excuse my somewhat newbie question but I am failing time and again to view full images in Plucker. For example I used the link posted on MobileRead for comics:http://www.turcic.com/avantgo/comics.shtml
and specified largest image size as 1000*1000 with 280 colors.
Now when I watch the page with Plucker on my Tungsten T3, images are cut to screen size, and I see no way to scroll through them or anything.
On the other hand I do know that some ducments of mine which have images in them give me the option to see it fully using scrolls when I double click on them.

Does anyone have a clue to what I am doing wrong?
