I dont understand... If you go in properties of the file, you will find there the width and height. You can divide width by height You will knot this way the ratio. After you decide about the width of the image in the html page after you divide the new width with the ratio you've computed above and you will get the new height. If you want to know how much to put an image in a html webpage, you first decide about the webpage width and after choose an ratio to put the image in. For example if I have a 960 page and I want the image to be 1/3 from this, so the width of the image will be 320. ----- Original Message ----- From: Homme, James To: programmingblind@xxxxxxxxxxxxx Sent: Wednesday, May 05, 2010 10:43 PM Subject: HTML: Coding Correct Image Sizes Hi, Does anyone know of a utility that can look at an image file and tell you the sizes for height and width to put into your HTML?
