Images can improve the design and the appearance of a web page.
<img src="pic_trulli.jpg" alt="Italian Trulli">
<img src="img_girl.jpg" alt="Girl in a jacket">
<img src="img_chania.jpg" alt="Flowers in Chania">
<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.
<img> tag is empty, it contains attributes only, and does not have a closing tag.
<img> tag has two required attributes:
Formula
src - Specifies the path to the image alt - Specifies an alternate text for the image<img src=" url " alt=" alternatetext ">
The required src attribute specifies the path (URL) to the image.
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.
<img src="img_chania.jpg" alt="Flowers in Chania">
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:
<img src="img_chania.jpg" alt="Flowers in Chania"> If a browser cannot find an image, it will display the value of the alt attribute:
<img src="wrongname.gif" alt="Flowers in Chania">
A screen reader is a software program that reads the HTML code, and allows the user to "listen" to the content. Screen readers are useful for people who are visually impaired or learning disabled.
Formula
Image Size - Width and HeightYou can use the style attribute to specify the width and height of an image.
<img src="img_girl.jpg" alt="Girl in a jacket" style="width:500px;height:600px;">Alternatively, you can use the width and height attributes:
<img src="img_girl.jpg" alt="Girl in a jacket" width="500" height="600"> The width and height attributes always define the width and height of the image in pixels.
Always specify the width and height of an image. If width and height are not specified, the web page might flicker while the image loads. Width and Height, or Style? The width, height, and style attributes are all valid in HTML. However, we suggest using the style attribute. It prevents styles sheets from changing the size of images:
<!DOCTYPE html> <html> <head> <style>
img {
width: 100%;
}</style> </head> <body> <img src="html5.gif" alt="HTML5 Icon" width="128" height="128">
<img src="html5.gif" alt="HTML5 Icon" style="width:128px;height:128px;"></body> </html>
Formula
If you have your images in a sub - folder, you must include the folder name in the src attribute:Formula
< img src ="/images/html5.gif"alt="HTML5 Icon" style="width:128px;height:128px;">Some web sites point to an image on another server. To point to an image on another server, you must specify an absolute (full)
