Megapixels is sometimes needed

      Even if small pictures are ideal on the web, taking big ones
      and then reducing them in size can be very good indeed -
      most cameras have various picture size settings, or you can use
      a program like GIMP and change the picture's size (GIMP
      is available free, gratis and for nothing, and there are versions
      for all major OS, including Linux, OS X & Win).

      If your digital camera takes decent pictures at dusk/dawn
      it most likely has a low pixel density (big pixels), or very advanced
      electronics, as noise becomes more and more a factor the smaller
      the light-sensitive chip is. Especially at high ASA/ISO settings
      this is very visible! So cramming a lot of pixels onto a small chip is
      problematic from a noise point of view.

      Sometimes it can help to reduce the image size, in post-processing,
      as the random noise then tend average out.

      For instance, Olympus has a range of water-resistant digital cameras,
      which for each new version has higher and higher pixel density, as
      they try to cram out more and more Mps from the same size of chips.

      So while in good lighting the new are better, in bad lighting they
      definitely not,
      but reducing the size of the picture, as mentioned above, might help a
      lot!

      If you're photographing still life, or other fixed objects, like houses,
      landscapes
      or gems, another way round is taking a series of identical pictures,
      using a sturdy
      tripod and then merge them to one - there are programs available that do
      that,
      and they work great!

      PS But as Arne pointed out, taking lots of pictures at no cost at all,
      increases
      the chances for your taking a good one!

        I take a lot of photos.  I used to use film and then scan in the prints.  Here is what I have found.

        Most monitors have a relative fixed pixel size... the most common being .28 so even a 640x480 standard old VGA picture will fill a screen and be wallpaper. 

        The real problem comes when you want to PRINT out color photographs in fine detail.  That 640x480 that looked so great on your screen? guess what.. it will only print a photo about 2.5x3 inches before becoming blurry!  A 1.2mp camera can print an acceptable 5x7 picture, but if you want to print 8x10 with detail you need at least 3mp!

        We now have 5mp cameras and they are just beginning to approach the clarity of film.  Whoever said Megapixels is not important does not fully grasp the full scope of digital cameras!

        I am an owner and moderator of several groups and I AGREE that people should upload smaller size pics to the photo albums or full size pics at 640x480 resolution. 

        I recommend the following TOTALLY FREE software that will let you do most anything to your photos...

        Editor's review of IrfanView


        4.0 stars"Simple, fast, and free"



        Reviewed by:

        CBS Interactive staff

        Reviewed on: November 9, 2008Version reviewed: IrfanView 4.25
        This
        image viewer and editor is a longtime favorite among our staff, and
        with good reason. IrfanView is simple, fast, and free for individual
        use. Upon installation, the app attempts to install two Google
        programs, but you can opt out.

        The program lets you open and
        edit images, as well as multiple media formats. You can cut and crop
        images, apply batch conversions, add, sharpen, or blur effects, create
        panoramas, and change color modes easily. The program continues to add
        support for an array of file formats and has plug-in support for most
        image, video, and sound formats, including MP3, AVI, audio CD, and WMA.
        The interface is far from fancy but should be easy enough for most
        users to figure out. An IrfanView Thumbnails shortcut on the desktop
        offers an Explorer-like file tree that quickly displays all images in a
        particular folder. The latest version includes a basic drawing palette
        made accessible by hitting F12. It contains simple Erase, Draw, Fill,
        Rotate, Draw an Arrow, and Color Picker commands, perfect for grabbing
        screenshots and highlighting image specifics.

        IrfanView does
        what it does well. It's not going to replace a major paint program, but
        why use a meat cleaver to cut a stick of butter?

        You can get it HERE  http://www.irfanview.com/%c2%a0 there are no pop-ups or ad-ware and it is totally free!
        I hope this helps someone,
        Andrew

        Even if small pictures are ideal on the web, taking big ones

        and then reducing them in size can be very good indeed -

        most cameras have various picture size settings, or you can use

        a program like GIMP and change the picture's size (GIMP

        is available free, gratis and for nothing, and there are versions

        the light-sensitive chip is. Especially at high ASA/ISO settings

        this is very visible! So cramming a lot of pixels onto a small chip is

        problematic from a noise point of view.



        Sometimes it can help to reduce the image size, in post-processing,

        which for each new version has higher and higher pixel density, as

        they try to cram out more and more Mps from the same size of chips.



        So while in good lighting the new are better, in bad lighting they

        definitely not,

        but reducing the size of the picture, as mentioned above, might help a

        lot!
