Looks very good.
But only problem I have, it does not work with vbulletin anymore.
With version 3 of highslide i can switch through all images in a thread. With version 4 the first image pops up correctly, but the next image, using the next or previous button, opens in a new window.
Hope, you understand me and I hope, that the reason is, because it's a beta version.+
Kind Regards, Stoebi
