Images are absolutely critical to making appealing and engaging websites. Can you imagine the web without them? No cat memes. No animated dancing bananas! No Instagram, at all. The internet would be a pretty boring and sad place!
In this lesson, we will be discussing how to include images in your HTML, along with some important attributes of the tag. With images, you can make your web pages much more engaging and visually appealing.
imgtag and some of its attributes,
Images are inserted into HTML using the
img tag. The tag can display a variety
of image types, including animated GIFs, bitmaps and vector graphics, though
most often, the images we see on the internet are JPEG and PNG files.
img tag is self closing, meaning it doesn't wrap around content or text.
Instead, the relevant information is stored in attributes within the tag itself.
There are two main attributes,
src, the source of the image, and
imgtag and some of its attributes,
src attribute provides the relative path or URL to the image file we want
to display. The image file can be local, say, for instance, if you're
publishing a website and have a local stored in a folder, your source may look
However, it's very common, even when publishing your own websites, to have images hosted somewhere else on the internet. In these situations, we need to provide a full URL as the source:
src attribute is always necessary. Without it, the
img tag has
nothing to display.
alt attribute contains text relevant to the image we're displaying, and
will appear in its place if the image fails to load.
While it isn't required, it is highly recommended that every image includes an
alt attribute. The
alt text is important for screen readers for the visually
impaired, as the text will be read out loud to the site visitor. It is also nice
to provide some sort of message to a website visitor if the image fails to load,
especially if the image is relevant to the rest of the content. Alt text on a
failed image will appear along with a small 'broken image' icon:
To include an
alt attribute, add it in along with the
<img src="https://i.imgur.com/H1qsYEl.png" alt="comedic crow gets wholesome support">
One additional attribute that can be useful is the
title. Content added to
this attribute will display when we hover over the image with our mouse. If we
were creating an
img tag with
title for a company logo, it
might look something like this:
<img src="../images/my_company_logo.png" alt="my company name" title="We're here to help you!">
When a visitor to your company site hovers over the logo, they'll see a message appear saying 'We're here to help you!'
title attribute isn't necessary and is often left out, but can be a nice
detail to include.
It's time to practice creating some images! For this challenge, feel free to use any images you'd like - the tests are looking for the correct tag and attributes, not the content. If you're not sure what to use, feel free to use the following URL as your source:
Your challenge is to write three image tags:
learn and read the tests as you go. When you've passed all the tests, run

With images, we can fill our web pages with visual content in addition to text. Brand logos, animated instructional guides, personal artwork and photography, or pictures of you and your friends - you now have the ability to create visually appealing content of any type!
