Inserting an image into a web page is a fundamental task that every web developer needs to know. The basic HTML structure for inserting an image is the img tag.
The img tag is a self-closing tag, which means it doesn't need a closing tag. This is different from other HTML tags that require a closing tag, like the p tag.
The src attribute of the img tag is where you specify the location of the image file. This is where you put the URL of the image file.

Image Properties
Image Properties are crucial for rendering images properly on a web page. The src attribute specifies the location of an image file, and it's essential to use the correct file path to ensure images display correctly.
The 'alt' attribute provides alternative text when an image fails to load, enhancing accessibility for users with slow connections or visual impairments, and improving search engine indexing and ranking capabilities.

You can control image dimensions and style using HTML attributes like width and height, which specify the width and height of the image in pixels, and style, which allows you to specify CSS styles for the image.
Here are some common attributes used to control image dimensions and style:
- width and height: These attributes specify the width and height of the image in pixels.
- style: This attribute allows you to specify CSS styles for the image, such as border, margin, and padding.
Image Size and Style
You can control an image's dimensions and style using HTML attributes. These attributes can be used to resize an image, but be aware that this can affect the image's aspect ratio.
The width and height attributes specify the width and height of the image in pixels. For example, setting the width to 500 pixels and the height to 300 pixels can affect the image's aspect ratio.
You can use the style attribute to specify CSS styles for the image, such as border, margin, and padding. For instance, adding a 1-pixel black border with a 10-pixel margin can enhance the image's visual appearance.

Image Attributes
Image Attributes are crucial when inserting an image into a web page. The alt attribute provides alternative text when an image fails to load, enhancing accessibility for users with slow connections or visual impairments.
The src attribute specifies the location of an image file, and it's essential to specify the correct file path to ensure the image renders properly. You can use relative or absolute paths, but make sure to get it right.
Here are some common image attributes:
You can also use the style attribute to specify CSS styles for the image, such as border, margin, and padding.
Width and Height
Specifying the width and height of an image is crucial for a smooth user experience. By setting the width and height attributes, you can ensure that the browser allocates the correct space for the image before it's loaded.

The width and height attributes are given as integers without a unit, representing the image's width and height in pixels. You can use these attributes to specify the actual size of the image in your HTML.
Specifying the image size in HTML helps the browser avoid moving surrounding content when the image is loaded. This is especially important for users who have already started reading the text.
Here are some key points to keep in mind when using the width and height attributes:
Don't use the width and height attributes to resize images, as this can affect the image's aspect ratio and lead to a poor user experience. Instead, use an image editor to put your image at the correct size before uploading it to your webpage.
Srcset Attribute
The srcset attribute is a powerful tool for optimizing images on your website. It allows you to specify a list of image files to use in different situations, such as high-resolution devices.
This attribute is particularly useful when you want to provide a high-resolution version of an image for devices that can handle it. For example, you can include a srcset attribute with a reference to a high-resolution version of the logo, as shown in Example 2.
The src attribute is ignored in user agents that support srcset when w descriptors are included. This means that if you include both a src and srcset attribute, the srcset attribute will take precedence.
Here are some common values for the srcset attribute, as shown in the Attributes table:
- URL-list: specifies a list of image files to use in different situations
- URL: specifies a URL to use for the image
By using the srcset attribute, you can ensure that your images are loaded efficiently and effectively, regardless of the device your users are on.
Examples and Best Practices
The correct HTML for inserting an image can be a bit tricky, but don't worry, we've got you covered.
Using the `img` tag is the most straightforward way to insert an image into your HTML document. This tag requires a `src` attribute to specify the location of the image file.
The `alt` attribute is a must-have when inserting an image, as it provides a text description of the image for users who can't see it, such as those with visual impairments. This text will also be displayed if the image can't be loaded.
You can also specify the width and height of the image using the `width` and `height` attributes, but be aware that these values should match the actual dimensions of the image.
The `border` attribute is not recommended, as it can be removed by the user's browser, and it's generally better to use CSS to style your images.
