Whenever I save an image in Adobe Fireworks at 72px pixles/inch, it keeps changing it to 71.12px (rounding it up to 28 pixles/cm) and its getting so annoying because whenever I have to paste an image within an image is asks me if I want to re-sample or not. I know its only a minor change but its a change all the same and I need to fix it. Any ideas??

    My suggestion is to use photoshop to do your work. If you have fireworks, you more than likely have photoshop. Fireworks is not the best for image manipulation, it never has been.

      Photoshop does not have PNG32, nor can it optimize image file sizes anywhere near fireworks. For example, the same image in photoshop being saved at its best optimization level for PNG with zero reduction in quality is DOUBLE the file-size for a flattened PNG in fireworks.

      Your right Photoshop IS for image manipulation whereas fireworks is for WEB DEVELOPMENT.
      After trying to troubleshoot my issue and locate the problem I've noticed it only happens when I flatten a PNG file. If I open the file again it will no longer be the 72 pixle/inch I saved it as, instead it'll be 71 point something.
      I've just checked and its done this to nearly a whole website I'm working on and I need to fix this urgently now because I can't work like this.

      Photoshop is not an option for me but thanks all the same.

        Believe it or not Photoshop does have PNG32, it is just not called PNG32... its called transparency...read to learn more..

          Interesting.
          Guess I just prefer fireworks.

            I think I may have worked out why it happens. Basically, saving a normal PNG file is totally fine and opens up exactly how I saved it, however, when I FLATTEN the PNG Fireworks obviously thinks that no more edits are going to be made on the graphic so for some reason it will take 0.088 off the resolution which is invisable to the naked eye anyway. (72px/inch will change to 71.12px)
            I can't believe I've never noticed this before with all the websites I've made in the past although I must admit, I've been more conscious of image file sizes recently, always aiming for the smallest possible file-size with the best quality. Maybe this is why I've only just started to notice it... who knows.

            I guess its lucky I always keep an UNFLATTENED version of every image I create in a seperate 'assets' folder.

            Just to be clear, I've always found that a FLATTENED PNG image in Fireworks produces the smallest file-size possible for a graphic with 100% quality.

            Thanks for your help guys.

    Hi,

    I believe that somewhere in the preferences you will find an option to switch the defaults from metric to standard. However, I wouldn't even worry about it too much. No big deal if the resampling prompt comes up, just say no.

      If I don't resample it, it will be a pixle too small, if I do sample it, it will stretch the image by a pixle. BOTH are not good and I can't let it just slide because its only a minor difference because I'm a perfectionist and its bugging me like mad. I can't find the metric to standard settings you talk of... you sure thats not photoshop your referring too?
