No i don't think it's possible to view images with a resolution that large, use an image batch converter and convert them to smaller resolutions. Correct me if im wrong. Well i know that DSOrganize cant.
I'm pretty sure it can read images that large since most of my images are huge...10+Mb each (Yeah i know, i haven't converted it yet...too lazy). Image viewer does a good job of viewing them EXCEPT when you zoom to 100% then it lags.
