    hello

    this is the example: http://www.lurati-sa/temp/bordini.png

    as you can see (well, as *I* can see in my firefox and explorer) there are
    several white dots around the letters, even if I changed the palette and
    set the proper value to be transparent (white color)

    what can I do to "clean" it?

    Of a broken URL, it seems.

    No, we cannot see. Even if we could see your jpeg image, so what?

    Do you have an HTML related question? With some real HTML, maybe? Well,
    your problem is more probably about CSS, so we would need to see both
    HTML and CSS as well as your description of what you expect to happen.

    Indeed.

    It is most likely a PNG image.

    I suspect this is neither about HTML nor CSS, but rather about PNG
    transparency. I furthermore suspect that the non transparent pixels are
    not exactly white.

    sorry but I double clicked the link and the picture is properly shown
    just in case, this is the website: www.spazioyoga.ch
    (please note: in firefox the alignment is ok, Explorer makes a mess: I'm
    working on it)

    maybe. I edited the palette, that's 16-colors, changing all near-whites in
    full-whites
    following your tip, I'll try changing also light-reds into full-whites,
    thank you

    Hmm, the domain lurati-sa can't exist, as the TLD is missing. The link
    should be <http://www.lurati-sa.com/temp/bordini.png>.

    The image on <http://www.spazioyoga.ch/> is a GIF image.

    It's possible that the undesired colors are a relict of GIF dithering.
    However, I don't know how to best remove these pixels--you may consider
    asking in a forum/newsgroup related to image editing.
