Rated 5 out of 5 stars
I have been looking off and on for an extension that would duplicate Opera's slideshow feature (and hopefully be better) - this feature was the only reason for me to use a browser other than Firefox.
Finally! - I came across this extension. It allows you to view all the images that a page links to, in succession, without having to return to the "index" page. You've got a manually controlled slideshow that can be operated in fullscreen with keyboard shortcuts or (with FireGestures) mouse gestures. It duplicates Opera's feature with improvements: it does not get "stuck" when an image link is redirected or when it leads to an html document.
I haven't used the other features much but so far the "save all images" works fine for me and so does the "view all images" unless I have CSS customized with Stylish (which I usually do).
I am amazed at all the complaints about this EXTREMELY USEFUL extension. I'm not saying it's perfect, but I still give it six stars for what it can do!
