IMAGES
Keep your web site fresh by publishing images on a regular basis.
Share your images, collections, and important photo memories
online.
When
submitting photos for posting online, you do not need nearly
as many pixels as you do for printing. Having too many pixels
makes it difficult to view photos on a monitor and it makes
the file size much larger, something you need to avoid when
posting photos on the Web.
Remember, not everyone has a high speed Internet connection
or a large monitor, so sizing photos down before sharing them
is the courteous thing to do. The recipient can always ask for
a larger file if they wish to print it--this is always better
then sending large files without asking first.
When submitting your photo's to be put on the Web or sending
them by email, the smaller you can get them, the better. There
are three things you can do to make your pictures smaller for
sharing online: Crop Change pixel dimensions Use compression.
In most cases, you will want to do all three of these things.
Since PPI and DPI are only relevant to print size and quality,
when dealing with digital photos for the Web, you need only
look at pixel dimensions. Most computers today have a monitor
resolution of 1024x768 pixels, so your images should be sized
no larger than this for on-screen viewing.
Older computers have a lower monitor resolution, usually 800x600,
so keep that in mind as well. The smaller the pixel dimensions
of an image, the smaller the file size will be. When sharing
photos online, 800 by 600 pixels is a good average size to go
with. If you wish to reduce file size even further, reduce your
images down to 640 by 480 or even 320 by 240. If you're sure
your recipients or Web site visitors won't mind waiting a little
longer, you may want to go as large as 1024 by 768, but anything
larger than that is going to be too large to see in the majority
of computer monitors without scrolling. File compression is
another way to make your photos smaller for online use.
Most cameras and scanners save in the JPEG format and this format
utilizes file compression to keep file size down. Always use
the JPEG format for photographic images you will be sharing
online. It is a standard file format that any computer can read.
JPEG compression can be applied at various levels, with image
quality and file size having an inverse relationship. The higher
the compression, the smaller the file, and the less quality
it will have.
