Sherrie,
What I did with the two that I sent you was to resize them using an image editor program. I am currently using Paint Shop Pro 7. There are many different ones out there and I would guess that most of them have the ability to resize an image.
The other way is to change the size as you display it on the web page. That is done in the HTML tag for the image. For example here is the studio1.gif file as it is on my web page, and I've shown the code to display it below the image. I'm sure this is familiar.

Now I can resize it just by adding something to the code. I take the largest dimension, which is the width, and change it in the img tag. It was normally 100 and I'll change it to 70. Like this...
<img width=70 src="http://www.wdwinfo.com/sites/brazeal/studio1.gif">
<img width=70 src="http://www.wdwinfo.com/sites/brazeal/studio1.gif">
You will see that it also changes the height to keep the same width to height ratio.
The only problem with the second method is that the file size (in bytes) remains the same. By using the image editor, as the image is reduced in width and height, the byte size goes down too; sometimes quite dramatically. Point your mouse at the images and right click, and then select properties. You will see that the file referenced is the same file and that the file size in bytes hasn't changed but the image size has.
