HACKER CLUB 4 U: WebPage Into Image

Note: this post initially linked to a Greasemonkey script that no longer works, but it now offers an easier solution suggested in the comments.

Unlike other photo sharing sites, Picasa Web Albums offers a way to download an entire album, but that requires Picasa 2.5 or later. If you don't want to install the application or you use Mac or Linux, there are other ways to download a photo album.

For Firefox, you can use DownThemAll, probably the best download manager add-on. After installing the extension and restarting the browser, go to the album you want to download, click on the "RSS" link from the sidebar and you'll get the album's feed. Right-click on the page, select DownThemAll/DownThemAll in the contextual menu, expand the Filters section and check "Images". Don't forget to enter the folder where you want to save the photos.

Update: comments to find a lot of interesting ways to download albums from Picasa Web.

While we wait for the option to save a web page as a PDF, due by Firefox 3 final release, there is another option for sharing and archiving web pages. Save As Image, is a simple yet useful Firefox extension developed by Rowan Lewis that adds an option to Save Page as Image to the File menu. When you select it you have the option to select a particular area of it and tweak it manually with dedicated text boxes provided. At least in theory. The selection overlay that should appear over the actual web page image, appears below it which makes it useless. I’ve contacted Rowan on this and hopefully he will take some time to either fix it or remove the selection features and make it a simpler save-whole-page extension.
With options to choose the image format (JPG/PNG) and image quality I find it extremely useful and, even with the image large size (specially when saving as PNG), still a better alternative to HTML versions that I would like to see available by default in Firefox as another option in the Save Page As… dialog. Being only 10KB (including the user interface) it shouldn’t be a big overhead. Options to save several tabs in a single animated PNG (which will be enormous) and a grayscale would be great to have as well.
