Lesson 5: Graphics
Putting A Picture On The Web Page
The img tag puts a picture on a web page. It is a single tag so does not require a closing tag:
The img stands for "image", src is an attribute, it tells the browser where to find the picture. The stuff in the quotation marks is the file name of the graphic which also includes the graphic's format extention (.jpg). Replace filename.jpg with the file name of your picture and be sure it’s between the quotes.
To keep things simple, for now store your pictures in the same place as your web pages, for example if you keep your HTML files in a folder called "my pages", put your pictures there too.
Every picture on a web page has its very own img tag:
That will put two pictures side by side on the page:
If an img tag is enclosed between the opening and closing p tags, the other image will start on a new line:
Give your pictures a description by adding an alt attribute to the img tag like so:
The alt attribute will make the description appear if a browser does not display images. In some browsers the description will also pop up when a mouse pointer is moved over the picture.
The two most widely used image formats are either the gif or jpg format. The gif format is suitable for pictures with solid blocks of color such as charts, or when an image requires a transparent background. The jpg format is suitable for pictures with subtle color changes such as photos.
