Simply specifying a smaller height and width for 
a picture in html will not make the file size 
smaller.  That is why it takes a long time for 
the page to load.  It also makes the web page 
seem sluggish since the browser does have all the 
full size pics in memory.  I don't know about 
Netscape, but changing the height and width 
parameters also makes the picture seem more 
pixelated. (For example, Art Shop Rose's eBay 
auctions look MUCH better if you save the image 
to your hard drive and then view it outside the 
browser.  Maybe that's why I got a Washu cel for 
so cheap, heh.)

So, just grab a program like paint shop (Version 
4 [up to 4.12] will still let you use the 
shareware version after 30 days) and resample the 
pics down to a smaller size.  (A simple resize 
will just make the thumbnail pixelated).  You'll 
have twice the number of picture files, but it'll 
take much less time to load.

If you look below, you can see what I mean.  On 
the left is what changing only the width/height 
parameters in html do.  On the right, is what 
creating a new thumbnail in a graphics program 
would look like if done properly. (i.e. 
resample)  In general, it's always a good idea to 
sharpen pictures that are shrunk down.

I'm still in the process of sharpening all of my 
thumbnails, and you can see a definite difference 
in the thumbnails that I forgot to sharpen on my 
Tenchi page.  Later.
