Just use Column view in the Finder! You can preview all sorts of images in the Finder, in the format you just described. Find your folder of pictures in column view, and then click on them. A preview of the picture will show up in a new column. It also might not suffer from the same small picture bug that Preview does, although I've never seen this problem in Preview.
