    Reviewing 0.6 (Aug 15, 2016)

    Downloaded but was caught by Norton as a Reputation issue.
    Submitted to Virus Total and Mcafee does not like file though Norton did.
    Submitted file to Norton directly and is now White Listed.
    Authors websites listed are both blocked by Norton as dangerous.

    Have contacted the author about this and would hope he follows through with submitting his own programs for White Listing and to cleanup his website for what ever issues are there and or has been reported.

    Will follow up with a review on the program but doing the authors job was not planned in timeline.

    For all people interested that run Norton you can submit files for checking here if suspected malware etc or
    if suspect is clean can submit here

    Best to notify author as is his job.........

    Very good tool for interactive optimizations, and quite fast too.
    For batch optimizations, I rather prefer FileOptimizer ( which has a broader file type support.

    I personally think RIOT is a fantastic tool and helps me a lot.

    @taxis: pngout can be used within RIOT. It is integrated as an external optimizer. The color quantization in RIOT will help further decrease your filesizes along with pngout.

    @Plumber: actually your review is a bit ridiculous. the plugin works as designed, because the image used internally in XnView is sent, not the image form the file. You may have altered the image by using a filter or cropping, so the plugin integration serves this purpose., You can't do that with an external tool.

    About bath being a garbage I disagree.How do you want the height to be populated for a bunch of images of different sizes ? For what image should RIOT populate the height ? You are asking an impossible think. The aspect ratio is kept if you check that option, so I don't understand your concerns. The image is simply fitted into the given rectangle while keeping aspect ratio,

    So make your changes then open your images straight from RIOT. Otherwise the last settings will be used. I heard the author prepares an automatic mode, where you don't need to change settings, they are chosen automatically.
