Bhavitha Cherukuri: HTML Images

HTML Images

Images can improve the design and the appearance of a web page.

FOR Example:

<!DOCTYPE html>
<html>
    <head>
        <title>
            Dog
        </title>
    </head>

    <body>
        <p>The alt attribute should reflect the image content, so users who cannot see the image get an understanding of what the image contains:</p>
        <img src="images/cutedog.gif"
        alt="cute dog" width="200">
        
    </body>
</html>

A new webpage opens with the image that has been selected as above:

HTML Images Syntax

The HTML <img> tag is used to embed an image in a web page.

Images are not technically inserted into a web page; images are linked to web pages. The <img> tag creates a holding space for the referenced image.

The <img> tag is empty, it contains attributes only, and does not have a closing tag.

The <img> tag has two required attributes:

src — Specifies the path to the image
alt — Specifies an alternate text for the image

Syntax

<img src="url" alt="alternatetext">

The src Attribute

The required src attribute specifies the path (URL) to the image.

Note: When a web page loads, it is the browser, at that moment, that gets the image from a web server and inserts it into the page. Therefore, make sure that the image actually stays in the same spot in relation to the web page, otherwise your visitors will get a broken link icon. The broken link icon and the alt text are shown if the browser cannot find the image.

Example

<!DOCTYPE html>
<html>
    <head>
        <title>Image</title>
    </head>
    <body>
        <img src="images/nature.jpeg" alt="nature" width="200" height="200">
    </body>
</html>

A new webpage opens with the nature image that has been inserted as above:

The alt Attribute

The required alt attribute provides an alternate text for an image, if the user for some reason cannot view it (because of slow connection, an error in the src attribute, or if the user uses a screen reader).

The value of the alt attribute should describe the image:

Example

<!DOCTYPE html>
<html>
<body>

<h2>Alternative text</h2>

<p>The alt attribute should reflect the image content, so users who cannot see the image get an understanding of what the image contains:</p>

<img src="images/Icecream.jpg" alt="IceCream" width="460" height="345">

</body>
</html>
