    I have worked whole day to make a very simple logo in Photoshop 5 and
    PS levels. After managing to make it almost as as I like, I tried
    using export gif 89 to make it transparent such that I could use it on
    different background colors. The result was an ugly transparency with
    white pieces visible around texts. One may think I have cutthe white
    background badly. Is there any tricks which I ma not aware of?

    This is caused by anti-aliasing on the logo, which you do want to keep
    it from being jaggy. The problem is you need a "matte" color which in
    later versions of Photoshop is easier to do.

    Try this: select a color that is close to what you think your major
    background color will be. Make a layer underneath the logo and fill with
    this color. Ctri-click on the logo in the Layers Palette to make a
    selection and inverse the selection (Shift-Ctrl-I) hit Delete. Now merge
    the the layers. Export as gif. Your white halo will now be similar to
    the background color of your page and give the illusion of fading into
    the backgound better.

    If you are going to use it on a wide variety of background colors you
    may have to make more than one version.

    You might also play with expanding the selection afterwards a few pixels
    to capture only the fuzzy edge and make it trasparent outside that if
    it's going on top of a pattern or background image. This is after
    following the steps described by edjh.
