Re: OT: img size width question ...

I have tried setting both width and height, even setting both exactly the
same as the original image dimensions. The results still come out wrong
(and the same amount wrong) on every computer and every browser.

I have also tried the "style="width: 270;" code and the results are
exactly the same as width= only. Nothing that I have tried gives a
result even close to the same as the original image or desired width
specification. I even tried creating a simple html code to display the
original size and the result is incorrect on every computer and every
browser ... to wit:

See the results here: http://www.upquick.com/temp/4x3results.jpg

The original test image is 400 pixels wide by 300 pixels tall.
Below is the actual html code I used to test the results:
------------------------------------

Test image size integrity.<br>
The original is 400 pixels wide by 300 pixels tall.<p>

Image 1 below left width=200. &nbsp; &nbsp;
Image 2 below right width=300.<br>
Image 3 at the bottom is actual size 400.<p>

<img src=4x3.jpg width=200> &nbsp; &nbsp;
<img src=4x3.jpg width=300><p>
<img src=4x3.jpg width=400><p>

--------------------------------------------------------
4x3results.jpg is a screen shot of the html code results:
Image 1 screen shot actually measures 278x211 pixels
Image 2 screen shot actually measures 582x536 pixels
Image 3 screen shot actually measures 775x586 pixels

It doesn't matter what monitor the html code is viewed on or what browser
is used. The resulting image sizes are never the same pixel width (and
dimensions) of what is specified by the 'img src' width or even the image
original.

All of the results are wacko.

Why?

How can I specify image size width and/or width and height that will
display at the specified size on SOME computer monitor with SOME browser?
