I understand there are a good few plugins that allow you to click thumbnails to see the full picture (usually with some 'fancy' zooming-in effect). Is there a plugin that allows you to click on a small-resolution image to enlarge it by 100% each time? This would be useful for blogs that specialise in pixelart (allowing clarity of display as long as the resolution is a multiple of 100), and in fact I believe this sort of measure is already used on websites like Pixelation.
