  1. I took the picture on the right and brightened it, and now it's lighter. Magic? filename? Maybe transparency?

    Less contrast = less colours = smaller palette is my guess. There are lots of ways you can slightly influence the file size.

    Unless you can find a program to save a TIFF at a specific size, your could try making small adjustments until you reach your target size.

  2. PM entries OK with me, but PollPaddy not, because it is an external site, that means you sing-up the PDN forum, and don't vote through it, so you can vote more than once in those kind of sites by deleting your history or using another browser,

    If they're that desperate to cheat, they'll find some way, like creating a sockpuppet (assuming there aren't any post count restrictions on voting).

    and they don't support the IP address voting...!

    They do.

  3. If you've read the first message - I DON'T add a drawing. I only save an original image with the same format.

    When I open a text document in Notepad and save it without editing, I get the same file size. It is logical to expect the same result from the image editor... bt.gif

    File size is not the same as quality. The quality slider determines how much quality will be sacrificed in this save. Any quality you have lost before is gone forever and you can't even keep the benefit of a smaller file size.

    Once you open a JPEG image it's converted into a bitmap and any quality loss is similar to quality loss resulting from a scanned photo being torn. It may be a lower-quality image to anyone that sees it (just as it would be a low-quality image if it was taken with a shaky camera), but that doesn't mean it has a smaller file size.

  4. That is, paint.net can improve bad quality? You think that this is possible? shok.gif That is, an source image with poor quality stores information about perfect quality? ap.gif

    If you open an 80% quality image, add a drawing on a new layer and save it as a 95% quality JPEG the file size will be larger and the drawing will be only slightly distorted, but the old image won't get any better.
