Your Height and Width settings are at 100%. If you want to take up less screen space you need to reduce those. However you are not going to get something that is exactly the number of pixels of your image.

W3Schools SVG tutorial.
I'm not sure why you would need to use SVG though. I would simply insert the image using a div if you didn't want to ttake up the whole screen.
Code:
<div class="image1"><img alt="" src="../Images/example.jpg" /></div>
with CSS:
div.image1 {width:100%; max-width:755px} *add whatever styling you want
