While I host my own image gallery plugin here (AWSOM Pixgallery), I’m not arrogant enough to think that it’s the only way to get images onto your website in a pleasing way. This image gallery plugin called Popup Image Gallery is actually very nice and has some great AJAX (Asynchronous JavaScript and XML) features (transitions between images, mouse-overs pop up images). It has one drawback though (in my opinion), no direct HTML links can be done to images since there isn’t a real “page” associated with any image (the pages are all built using JavaScript). However, it’s an interesting alternative to try out if you want slide show effects or other cute transition features for your images.
