Can I Reduce Header Height in Twenty Ten Theme?

Hi,

I just installed WP on my latest site https://slidingmitersawreviews.info/ and I like the default theme itself, but with the wide header image, the title space and the header menu, the content starts half way down the page – especially if visitors have half a dozen toolbars!

So I thought “no problem; just go and change the header height in the style sheet”, but it only gives the width, and I don’t know how to change the code to make it have a thin header pic.

When I tried adding an image of 940 width x 90 height, it would only let me upload a cropped image so it was the same dimensions as 940 x 198, the current size.

Please ignore the awful header image at the moment. I thought it looked good yesterday!

Anyone know how to make the header image only 940 wide x 90 px instead of 190 x 198 please?

Current header code in Stylesheet:

/* This is the custom header image */
#branding img {
	clear: both;
	border-top: 4px solid #000;
	display: block;
	border-bottom: 1px solid #000;
}

it says this in the header code:
` <img src=”<?php header_image(); ?>” width=”<?php echo HEADER_IMAGE_WIDTH; ?>” height=”<?php echo HEADER_IMAGE_HEIGHT; ?>” alt=”” />
<?php endif; ?>
</div><!– #branding –>`

thanks a lot
