OK, I think I got it: you have noticed that some recent browsers do
scale pictures at the time of rendering. Be careful, this is a feature
of _some_ browsers, not a general behaviour of all. You should not take
it for granted.

A picture is not defined by "100 dpi". This sort of definition is useful
only when you want to print it. A picture in HTML is defined by its size
(width in pixels by height in pixels) and by its "weight" (in kB =
kilobytes).

I would recommend you should use pictures no larger than about 720 px in
width and 540 px in height, so that they will fit nicely in screens or
windows of 800 x 600 and 1024 x 768. Additionally, the pict "weight"
(file size) should preferably not be much more than 50 kB for a quick
download, acceptable even on a dial-up.

Now you see that this "width=whatever" is useless. Let the user decide
what window size he has and how he wants to see your beautiful image.
I do use the attribute 'Width="100%"' in several of my pages, but this
is only to center the image on the screen. The complete tag is:
<TABLE WIDTH="100%" ALIGN="center" BORDER="0"> plus padding and spacing
if required.

If you want to center your table, give it a width of 100%. If you don't,
i.e. if you are happy with left-alignment, don't give it any width.
