Those using Firefox 3.0 may have noticed that by default when someone scales the content of a page, the images are resized too, a behaviour long-pioneered by Opera. Those using Firefox 3.0 on linux will be sorry to find out that upscaled images are not resampled using anything but what seems to be nearest neighbour (I haven't checked the code): they are ugly, pixelated and definitely not pleasant to the eye. This is well documented on the Mozilla Bugzilla repository and sadly it may be the case that it's not fixed until Firefox 3.0 final is out. Which is a shame, as many people with higher resolution displays, especially high-resolution laptop displays that sometimes reach approximately 150dpi actually depend on the scaling functionality to be able to read stuff properly. Ironically GTK+ offers pretty decent image scaling functionality and hopefully it's not that hard to make use of it in Firefox in the near future. Here's an illustration of the problem. The picture on the left shows the original (unscaled) content of the ΜΠΛΟΟΓΚΛ hellenic blog search engine. The one in the middle shows the scaled version, as shown in Firefox 3.0 Beta 5 that shipped with Ubuntu 8.04. The one on the right shows a resampled version of the image using the (pretty computationally expensive) lanczos algorithm, which although not probable as a solution it's quite close to the (realistically possible) bilinear resampling for upscaled images of this size.
