I took a picture off a website to use it as a bckground. Once I set it as
the background the picture showed up blurry and out of focus.I've tried
restarting the computer changing the size,number of pixels and nothing seems
to work.I've even saved the image as on of my pictures and still nothing
changes.I don't have this problem on any other of my systems and they all run
on windows xp.If youy can help me please respond asap the computer that has
the problem is my sisters new one and im trying to suprise her with a
completly setup copmputer.Thanks in advance to anyone who helps.
 
Place your mouse pointer over the file name or the thumbnail of the picture.
A box will open and will give you the dimension of the picture in pixels. To
fill your screen you need a fair number of pixels. Something like 1440 x 900
(this is my screen and your screen will probably be a little different). If
the picture you downloaded from the web site is something like 200 x 150
pixels, there is no way to fill your screen with it and indeed the picture
will look blury, pixilated and out of focus. Not unsual for pictures posted
on the web to have low pixels content.
To find out how many pixels you need to fill your screen, right click on
your desktop screen and click on Properties on the opening menu. Then click
on the Settings tab. You will see the Resolution of your screen listed there.
The closer you are to these numbers with the picture you have, the better the
picture will look on your screen.

I think this is one of the things associated with enlarging an image too
much.

Images for a website tend to be optimized for the size they will display
on that website and there are some very good algorithms to do that.

Enlarging a website image too much hits a barrier where it will show up
the blurriness and blockiness you may indeed be seeing.

A source image (especially for a desktop background for example)
approaching possibly 1 MB or more in filesize will probably be a lot
sharper (less blurry)
