When building an Office Live website with lots of images, it can be a bit of a pain to upload each image individually.
Instructions have just been updated on how to set up the mutliple image uploader. This has to be done from within the Image Gallery itself (as opposed to the Website section). Full instructions can be found here
Once the multiple image uploader is installed, it can be used to get all the images required into the Image Gallery, which can then be utilised within the website as needed. Note that within the website section, there is also now a new tool to automatically resize large images to make them more suitable for website use. Another great time-saving device.
