HTML Images

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

HTML Images Syntax

The HTML 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 tag creates a holding space for the referenced image.

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

The tag has two required attributes:

Syntax

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

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

If a browser cannot find an image, it will display the value of the alt attribute:

Example

Tip: 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.

Image Size — Width and Height

You can use the style attribute to specify the width and height of an image.

Example

Alternatively, you can use the width and height attributes:

Example

The width and height attributes always define the width and height of the image in pixels.

Note: 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:

Example

Images in Another Folder

If you have your images in a sub-folder, you must include the folder name in the src attribute:

Example

Images on Another Server/Website

Some web sites point to an image on another server.

To point to an image on another server, you must specify an absolute (full) URL in the src attribute:

Example

Notes on external images: External images might be under copyright. If you do not get permission to use it, you may be in violation of copyright laws. In addition, you cannot control external images; they can suddenly be removed or changed.

Animated Images

HTML allows animated GIFs:

Example

Image as a Link

To use an image as a link, put the tag inside the tag:

Example

Image Floating

Use the CSS float property to let the image float to the right or to the left of a text:

Example

The image will float to the right of the text.

The image will float to the left of the text.

Tip: To learn more about CSS Float, read our CSS Float Tutorial.

Common Image Formats

Here are the most common image file types, which are supported in all browsers (Chrome, Edge, Firefox, Safari, Opera):

Abbreviation	File Format	File Extension
APNG	Animated Portable Network Graphics	.apng
GIF	Graphics Interchange Format	.gif
ICO	Microsoft Icon	.ico, .cur
JPEG	Joint Photographic Expert Group image	.jpg, .jpeg, .jfif, .pjpeg, .pjp
PNG	Portable Network Graphics	.png
SVG	Scalable Vector Graphics	.svg

Chapter Summary

• Use the HTML element to define an image
• Use the HTML src attribute to define the URL of the image
• Use the HTML alt attribute to define an alternate text for an image, if it cannot be displayed
• Use the HTML width and height attributes or the CSS width and height properties to define the size of the image
• Use the CSS float property to let the image float to the left or to the right

Note: Loading large images takes time, and can slow down your web page. Use images carefully.

How to Add Images in HTML From a Folder

Have you seen any websites without images? Yes, we still might get a few, but they are rare these days. Let’s learn how you can add images to HTML documents.

Modern web relies hugely on images relevant to the site content as this helps to improve the website appearance and helps readers to understand the content better.

A website can contain multiple images that are often organised in the subdirectories and folders. Thus, it’s important to learn, how you can include an image in an HTML file from a folder.

The HTML tag

You can include an image in HTML using the HTML tag.

img src="flowers.jpg" alt="A Flower Bouquet"/> 

The loads the image and places it on the web page. It has 2 important attributes:

• src — Specifies the source location where the browser will look for the image file. Once it gets the image file, it loads the image on the web page. We can use a URL (Uniform Resource Locator) to display an image from another website.
• alt — Specifies the text we need to display if the image is unavailable or if the system can’t load the image. This text also helps visitors with disabilities using a screen reader.

How to set the image source in HTML

Let’s learn a bit more about how you specify the source of the image.

The base case is to specify the filename of the image that you’d like to place in the HTML document.

img src="flowers.jpg" alt="A Flower Bouquet"/> 

The browser will look for the image in the same folder where you’ve placed the HTML document.

If the image is located in a folder or a subdirectory, you need to include it to the source as well.

img src="/images/flowers.jpg" alt="A Flower Bouquet"/> 

After you’ve added the /images string to the source, the browser will look for the image flowers.jpg in it instead of the current directory.

How to add an image to HTML from a remote location

The images that you use in your HTML pages don’t have to be located next to them. You can easily add images from remote locations (other websites or file storages) using a URL.

img src="https://learn.coderslang.com/js-test-8.png" alt="JavaScript test"/> 

How to use “.” or “..” as the image source in HTML

You can instruct the browser to look for the image in the current directory using single dot . in the src attribute.

img src= "./flowers.jpg" alt="A Flower Bouquet"/> 

Or, if you want to move one directory up, you use two dots .. to ask the browser to start looking for the image one level above the current directory.

img src="../otherImages/flowers.jpg" alt="A Flower Bouquet"/>
