JAlbum for Windows and Mac users is a long-time favorite free Web album generator. There's no wizard to direct you through the process, but a quick look through the menus will be enough to get you started creating image collections online.
To begin, specify the original image folder, set the album-destination folder, select the images, and generate the album--it's really not more complicated than that. Using the integrated FTP client, you can upload your album to your Web site or you can use the integrated Web server to serve your album from your computer. The JAlbum site also lets you post your projects to their Web hosting service for free, as long as you don't mind registering your name and e-mail address. There are several great-looking templates and skins to choose from, with more skins available online from JAlbum.
Recent versions include a lot of new tools, notably a photo editor for basic manipulations such as red-eye removal and cropping. If you've been looking for a new way to post your photos, JAlbum is a great choice with an extremely easy-to-use interface and plenty of options to create the perfect album.
