WEBMASTER TIP - Image Resizing
 
Note: In code examples I add a period after each left arrow
bracket so the code can be viewed in all e-mail programs. If 
you copy and paste, be sure to remove the periods or it won't 
work.
 
Question: I read a tutorial on using HTML to resize images, 
basically it's just coding the wrong image size into the 
image. I tried it but the image doesn't look as good. Did 
I do something wrong?
 
Simon Says: Yes and no...if the image resized on the page 
then you didn't do anything wrong as far as following the 
tutorial you read, where you went wrong was following the 
tutorial in the first place.
 
Not all advice on the web is good advice. By simply changing 
the image size by coding an incorrect height and width into 
it, you're asking the browser to do something it was never 
meant to do, and that's to be a graphics editing program. The 
browser can resize the image, but it looks bad because the 
browser doesn't intelligently resize the image, it just 
scrunches or stretches the image with no deference to quality.

Besides that, if your resizing the image to a smaller size, 
just coding the image to the incorrect size doesn't make the 
download size any smaller. If you want smaller dimensions, 
you should also take advantage of the fact that reducing the 
image in a graphics editor will reduce the over file size, 
this making it download faster.
 
With free graphics programs available, and with resizing an 
image such a simple matter, there's no reason to use HTML 
to reduce the image size. Reducing it in a proper graphics 
editor will not only make the image download faster, but it 
will be of a higher visual quality too.
 
To resize an image in most graphic editors, all you do is 
open the image in the program and search the menu items for 
an option that says "Resample" or "Resize" -- or something 
similar.
 
I use Corel Photopaint. To resize an image in Photopaint I 
just go to "Image" on the main menu and "Resample" on the 
submenu. Then you just tell the program what size you want. 
Corel has an option to maintain perspective so the image 
won't distort by reducing it great in one direction than the 
other. With that option selected, when you change either the 
vertical size or horizontal size, the other direction resizes 
automatically, this prevent a distorted perspective.
 
Photopaint is not cheap, so unless you want to get serious 
about graphics you'll want to look for a free or lower cost 
alternative. I've featured a good free program below in the 
Software Spotlight, but there are many more to choose from. 
If the program I've listed isn't for you, just Google for 
"free graphics editor" or visit some freeware/shareware sites.

SOFTWARE SPOTLIGHT - Irfanview
 
Irfanview is a superb free graphics viewing program with nice 
editing features. In regards to Webmaster Tip in this issue 
about resizing images, Irfanview makes it very simple. Here's 
how:
 
1) Open the image by clicking File, then Open, and choose an 
   image.
2) With the image open, click Image from the main menu, and
   Resample/Resize from the submenu.
3) In the Resize dialog window, you'll see several options for
   resizing that are self-explanatory. Choose one and click OK.
 
4) The image is now resize, just save it and you're good to go.
 
Irfanview has many other minor editing features and options, 
play around and have fun. It's a great little program.

THE ODDBALL WALL - Wandering Wisconsin
 
On this day in 1836, the Territory of Wisconsin was created. 
Hey, let's see what you know about my home state!

Wisconsin is the ____ State. Fill in the blank.

3) Which Wisconsin Senator was the founder of Earth Day?

World Museum up close and personal. The funny thing is, the 
Circus World Museum isn't even located in Milwaukee. Where is 
it located?
a. La Crosse   b. Baraboo   c. Appleton

that make you wonder...for example, I wonder if the folks in 
Beaver Edge know which edge of the beaver their town is named 
after? Is Imalone pronounced "I'm alone" ...and is it right to 
call it that if more than one person lives there? Why would 
they build a town where it had to be called Pole Cat Crossing? 
And hey, I'm not even going to mention what comes to mind con-
cerning the towns of Breed, Butman Corners, and Spread Eagle!

COMPUTER TIPS - Live OneCare for Windows XP
 
Today's computer tip column will be a little different from 
most. It's a bit of a rant about what may turn out to be a 
great product that I don't want you to ever buy!
 
Windows Live OneCare runs in the background on your computer 
offering live antivirus protection, firewall protection, 
spyware protection, computer tune-ups, and file back-ups. It 
also monitors your computer's health and more. It may turn 
out to be the best program of it's kind.
 
Why?
 
Because it's made by Microsoft, the same people that make the 
Windows XP operating system. But wait - who better knows the 
operating system they want to protect than the company that 
makes it?
 
No one, so why not buy it, then?

Because most of it is fundamental, system level security and 
safety features that should be built into the operating 
system you've already paid for! What Microsoft is attempting 
to do here is like you buying a house from me, then me 
charging you a yearly fee to close the doors to burglars that 
I left open either through negligence, incompetence, or 
arrogant disdain.
 
It seems to me, this product represents a conflict of interest 
for Microsoft. How might they sell as many yearly subscriptions 
to Windows Live OneCare as possible? One way would be to make 
sure the Windows Operating system it's designed to protect 
remains vulnerable to the problems Live OneCare is suppose to 
protect against!
 
DID YOU GET THAT?
 
One way to maximize sales for Live OneCare is for Microsoft 
to ensure Windows remains vulnerable to the problems Live 
OneCare solves. In my opinion, this smacks of racketeering.
 
If they made a better operating system (OS) this product 
would be unneeded! By selling this product Microsoft is 
admitting the OS is flawed, but, they can protect your 
computer from their inherent flaws, for a yearly fee, and 
you're supposed to be grateful for that!
 
If Microsoft knows what the dangerous holes in their OS are, 
isn't it incumbent upon them to fix them for free rather than 
continuing to sell the OS as is and tacking on a subscription 
fee to finish the product?
 
Do you want to reward Microsoft for this kind of behavior?
 
I sure don't...but not everyone thinks like me. If you do, the 
only way for this kind of protection to be built into the OS - 
as it should be - is if Windows Live OneCare fails as a com-
mercial product, or if we cause a big enough stink Microsoft 
is forced to rethink their strategy. That's going to be an 
uphill battle, so we must unite. How?
 
1) Don't buy it.
 
2) Pass this article on to every Windows user you know.
 
3) Write or call Microsoft and complain, and tell them you're 
going to complain to your elected officials - then do it! 
Let's put as much heat on them as we can. Here's their contact 
page:
 
http://support.microsoft.com/contactus/
 
4) Go here:
http://firstgov.gov/Contact/Elected.shtml
 
...to find the phone numbers, fax numbers, mailing addresses 
and email addresses of the elected officials for your state. 
You'll find the information you need to contact your US 
Senators, Representatives, Legislators, Governors, and even 
the President - then complain to them. Just do it!
 
5) Go here:
http://firstgov.gov/Agencies/State_and_Territories.shtml
 
...to find your state's web site where you can locate the 
contact information for your attorney general and complain 
to him or her. Just do it!
 
6) Feel like doing more? Complain here:
 
National Association of Consumer Advocates
1730 Rhode Island NW, Ste 710
Washington, DC 20036
Telephone: (202) 452-1989 voice
Fax: (202) 452-0099
Email: info@naca.net
 
7) Complain to anyone else you can think of that might take 
action. Call in to talk radio shows. Write to newspapers. 
Make noise! Don't forget to pass this on to every Windows 
user you know so we can maximize our power -- the power of 
numbers.

this advice is your responsibility. Your computer, your choice.
