I've been testing out a couple of them like FastStone Image Viewer/Max Viewer and XnView but they all seem to have problems with displaying high res images in the range of 3000x3000 and above. When I view an image using good ol Windows Picture and Fax Viewer, everything seems to work fine and it's good at rescaling a high res image from it's original size to fit my desktop with minimal distortion. But that program is way too limited. Anyway, please recommend me a lightweight (e.g. doesn't need to have a batch converter or thumbnail display) image viewer that has simple features like the ability to magnify to actual size with the click of a mouse button and can hide pretty much all UI elements not related to the image itself (Maybe even the windows borders as well). Thanks.
