How does UXArchive handle...displaying images: At a fixed size, aligned constantly 200px from the top of my screen without ability to scroll down, effectively cutting all images in half. (standard 1200*800 laptop screen) There are other issues with the image popup, some times the images are displayed on 2 rows and some times on 1, still without any vertical scroll so i cant see the second row. When there are many images the horizontal scroll is annoying and sometimes my mouse wheel scrolls the background and not in the popup window. Keyboard navigation like next/previous buttons would be good. Otherwise a pretty good idea, you just need a larger collection of apps.
