If you are an IE user with a Dell widescreen notebook or a Dell that shipped with a hi-res widescreen display, IE may make images on web pages look more pixelated and awful than usual. This is particularly true on the Web-CAT wiki, for example. It looks like Dell may have "turned on" a feature of IE on such machines that tells the browser to auto-scale images proportionally to the larger font size that many users have selected. Read this blog entry describing the problem and how to fix it (and end your suffering :-) ).

I couldn't imagine why IE was showing pages that were so much uglier than other browsers on my laptop, until I noticed that it was scaling images. Further, since it would scale <img> tag images, but not background images, lots of sites looked weird because of the layout tricks so common on the web. After I turned off the image scaling, I was much happier! Of course, I still prefer Firefox, but now IE is a bit more tolerable to look at.
