How to place an image onto a web page |
|
Answer» An image can be inserted into the document using <IMG>. Use the src attribute to specify the URL containing the image. alt attribute (ALTERNATIVE attribute) is used to provide a brief description of the image. This alternative description should be written specifically for screen readers to read and for displaying when the image fails to download. Decorative images are best displayed as background images, but if we need to use a decorative <img> ELEMENT, INCLUDE the alt attribute, but leave it empty. Because a browser downloads each image separately, it needs to know the image’s height and width so it can create a placeholder for the image while the image downloads. Otherwise, after each image is downloaded and its real size becomes known, a browser has to reflow the PAGE. This slows the rendering and annoys the user. To set an image’s size, we can use the width and height attributes of <img> or the width and height CSS properties. Example: <img src="FILE.EXT" width="IMAGE_WIDTH" height="IMAGE_HEIGHT" alt="BRIEF_IMAGE_DESCRIPTION" /> |
