Imagine a site with a really big header image having a width close to 1000. The header allows sliding between several pictures, each representing a blogpost or item, that may be found on the site. Realising such a carousel is quite easy with jQuery. I built such a site and there where something like 14 such images and jQuery’s animation method suddenly behaved very strange. So i posted a bug, which is reported to be fixed with jQuery v1.5. If you can’t wait there’s a quick fix: use jQuery 1.4.2.
