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.

HTML Tag

The tag is used to embed an image in an HTML 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 has two required attributes:

• src — Specifies the path to the image
• alt — Specifies an alternate text for the image, if the image for some reason cannot be displayed

Note: Also, always specify the width and height of an image. If width and height are not specified, the page might flicker while the image loads.

Tip: To link an image to another document, simply nest the tag inside an tag (see example below).

How to Insert an Image in HTML Page?

Images make content more interesting by helping readers understand the content better on the web page.

We can insert images into the HTML page. To insert image in an HTML page, use the tags. It is an empty tag, containing only attributes since the closing tag is not required.

We should use the tag inside … tag. The tag specifies an image to be displayed in an HTML document.

The src attribute is used to add the image source which is the URL of the image(location of the file).

The alt attribute is for adding alternate text, width is for adding width, and height is for adding the height of the image.

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

The tag has two attributes −

• src − Specifies the path to the image(location of the file)
• alt − Specifies an alternate text for the image

Syntax

Following is the syntax to insert an image in an HTML page.

Example

Following is the example program to add an image to an HTML page.

DOCTYPE html> html> body> h2>HTML Article on Inserting image to the web pageh2> img src="https://www.tutorialspoint.com/javafx/images/javafx-mini-logo.jpg"> body> html> 
 

Now let’s see how the alt attribute (alternate text) works if the user for some reason cannot view, it because of slow connection, or an error in the src attribute. Then the value of the alt attribute describes the image property.

Example

In the following example program, we will specify an incorrect path for the image to be inserted in an HTML page and see how the alt attribute works.

DOCTYPE html> html> body> h2>HTML Article on Inserting image to the web pageh2> img src="https://www.tutorialspoint.com/opencv/images/opencv-mini-logo.jpg" alt="search engine image" > body> html> 
 

The text “search engine image” is the alternate text for the image when there occurs some problem to view the image.

Example: Changing the size of an image

We can also use style attribute to make changes in the size of the image that is height and width of the image. Following is the example program to make changes in the size of the image.

DOCTYPE html> html> body> h2>HTML Article on Inserting image to the web pageh2> img src="https://www.tutorialspoint.com/opencv/images/opencv-mini-logo.jpg" height="50px" width="50px"> body> html>

Adding images to your website or social networking profile is a great way to spruce up your page. The HTML code for adding images is straightforward, and often one of the first lessons for an HTML novice.

Sample HTML for Inserting Images

Inserting the Image

• Some blog-hosting services let you upload images using the blog administrator tools.
• If you have a paid web host, upload the image to your own site using an FTP service. Creating an «images» directory is recommended to keep your files organized.
• If you want to use an image on another website, ask the creator for permission. If she grants it, download the image, then upload the image to an image hosting site.

• If you are trying to insert an image on a forum, you can type directly in the post. Many forums use a custom system instead of HTML. Ask for help from other forum-goers if this doesn’t work.

Begin with the img tag. Find the point in your HTML body where you’d like to insert an image. Write the tag here. This is an empty tag, meaning it stands alone, with no closing tag. Everything you need to display your image will go inside the two angle brackets.

• If you uploaded the image to an images directory in your own website, link to it with /images/yourfilenamehere. If this doesn’t work, the images directory is probably inside another folder. Move it up to the root directory.

Place the URL in a src attribute. As you may already know, HTML attributes go inside a tag to modify it. The src attribute is short for «source,» and tells the browser where to look to find the image. Write src=»https://www.wikihow.com/Insert-Images-with-HTML» and paste the image URL in between the quotation marks. Here’s an example: [1] X Research source

Add an alt attribute. Technically your HTML has everything it needs to display the image, but it’s best to add an alt attribute as well. This tells the browser what text to display when the image fails to load. More importantly, this helps search engines figure out what your image is about, and lets screen readers describe the image to visually impaired visitors. [2] X Research source Follow this example, changing the text inside the quotation marks:

• If the image is not important to the page content, include the alt attribute with no text (alt=»»). [3] X Research source

Save your changes. Save the HTML file to your website. Visit the page you just edited, or refresh the page if you already had it open. You should now see your image. If it’s the wrong size or you’re unhappy with it for another reason, continue to the next section.

Optional Adjustments

Change the size of the image. For best results, resize the image using free editing software, then upload the new version. Setting the width and height using HTML tells the browser to shrink or expand the image, which can be inconsistent across browsers and (rarely) cause display errors. [4] X Research source If you want a quick and serviceable adjustment, use this format:

• (Number of pixels, or the more phone-friendly «CSS pixels» in HTML5.)[5] X Research source [6] X Research source
• or (Percentage of web page dimensions, or percentage of HTML element containing the image.)
• If you only enter one attribute (width or height), the browser should preserve the width:height ratio.

Add a tooltip. The title attribute can be used to add an additional comment or information about the image. For example, you can credit the artist here. In most cases, this text will be displayed when the visitor hovers the cursor over the image.
