<img src<img src="../../Photos/photos/cats/Annie.JPG" width="600" height="500" alt="" title="" border="0"
ok this is what I have. I want to make it smaller, for example I want the width to be 500, and keep it in proportion. So I put in 500 where width ="" . Now what do I put for height, or am I going about this all wrong? I feel like I'm getting close!

height="auto"

Yep, if you're using HTML then follow Eric's example above!

grr! typing auto gives me a straight line where the photo should be!

Use CSS in the head of the page as I posted earlier or try dropping the height from the image html. Some browsers are a little fickle how it's all done. You probably just saw the lack of height in the built in preview in the html editor.

Oh, it worked! Thanks so much! I just took height out and it came out perfect! Sorry for all the bother; I'd have a zillion more questions, but you've both been kind enough :Louise

Why not trial visual site designer? It it a much more robust and more up to date visual site creator like frontpage.

You could also use the insert image option in the Editor. (Top toolbar–looks like a Polaroid photo)
It opens a panel where you can browse to find your photo, set the height/width, alt text and title, alignment and border, create a link and/or a thumbnail image as well.

I like to size my photos in an image editor before adding them to the site, but the insert image thing comes in handy for determining the perfect size and trying out the positioning.

VSD is the way to go if you don't want to mess with the code.
