Inserting a Image Determine after what element in your WebPage you want the
Image to appear Place cursor in your code after the element Type <img src=“image.url”/> “image.url” is location of the file
http://www.server.com/images/image.gif ../images/image.gif images/image.gif image.gif
Hint To place image on a new line use <br/> before <img …/>
Offering Alternative Text
If the image won’t appear, the “alternative text” will <img src=“cat.gif” alt=“Picture of a cat”/> alt is REQUIRED for XHTML Can also use title attribute On some browsers “Alt” text will be a mouse over
pop-up Examples

Specify Size of Image
Tell the Browser how large the picture is to speed up loading
<img src=“image.gif” alt=“a picture” height=“100” width=“100” />
Quick Way Insert image in webpage without dimensions View page and right mouse on image Select properties and determine dimensions Modify img tag with the dimensions
Scaling an Image
Use new values for height and width attributes
CAREFUL –you must maintain aspect ratios or you will distort image Just set height or width and Browser will
automatically set the other Can also set to percentage of Browser
viewable space height =“ 50%” width = “50%”
Thumbnails
A thumbnail is a “mini” version of a larger image
<a href=“large.jpg”><image src=“mini.jpg” alt=“A thumbnail” height = “50” /></a>
Making Images “float”
You can float images in the text You can move image to the left or to the right
relative to text <img src=“image.gif” align=“right”> Use <p></p> after img tag to get text to “fill”
left over space Example

Stopping Elements from Wrapping Image
You can control how text & other elements “flows” around your images
<br clear=“left”/> (or right) Next element goes to first available margin on left
<br clear=“all”/> Next element goes to first available spot where
both margins are clear
Adding Space around Image
Create a buffer around your image <img src=“image.gif” alt=“a picture”
height=“100” width=“100” hspace=“20” vspace=“20” />
Aligning images NOTE: Not all directions work in all browsers Used to align images with text <img src=“image.gif” align=“direction”> Where direction is
TEXTTOP Top of image to top of text
TOP Top of image to top of tallest element
MIDDLE Middle of image with base of text
ABSMIDDLE Middle of image to middle of tallest element
BOTTOM Bottom of image to baseline of text
ABSBOTTOM Bottom of image to bottom of tallest element
Adding Horizontal Rules
A horizontal rule is a line across the Web page <hr/>
size=“10” (how thick) Width=“70%” Align=“left” or “right” or “center” noshade=“noshade”
