It is not that easy to download all images from a page with many images in Firefox. It would be possible to use a download manager or wget to get all the images but this would mean that you would have to rely on external tools and know how to use them. A far easier method is to use the Firefox extension Batch Downloader. It does exactly what the name suggests, it downloads all images that have a resolution of 200×200 or more in one batch to your hard drive.
