    Hi

    Is there a method to comress Jpg images so it will download quicker to the
    user's browsers?

    Thank you,
    Samuel

  3. The compression factor of Jpeg images is determined at the time they are
    saved, and is built into the jpeg standard. You can use any standard graphics
    application (for a free one, try "Paint.Net").

  4. Hi Sam -

    Please note that the higher you compress the JPG file, the more the
    quality of the image will degrade. You'll notice "blocky" areas or
    blotches.

    Depending on what the image is of, you may wish to change graphic
    formats. For instance, if you have a large gradient, you may be better
    off with a GIF file with 128 or 256 color depth and a dither.

    If you can get your hands on them, Adobe Photoshop or Adobe ImageReady
    are great tools for looking at the differences in compression and
    format side by side. Both products will also give you a size
    comparison, as well as estimate how long the image will take to
    download over a given connection speed.

    Cheers,

    -Mark
