This is an empty element meaning that it has no text content or closing tag that requires a minimum of one attribute to be useful — src sometimes spoken as its full title, source. So for example, if your image is called dinosaur. If the image was in an images subdirectory, which was inside the same directory as the HTML page, then you'd embed it like this:. Note: Search engines also read image filenames and count them towards SEO.
Therefore, you should give your image a descriptive filename; dinosaur. But this is pointless, as it just makes the browser do more work, looking up the IP address from the DNS server all over again, etc.
You'll almost always keep the images for your website on the same server as your HTML. Warning: Most images are copyrighted. Do not display an image on your webpage unless:. Copyright violations are illegal and unethical.
In addition, never point your src attribute at an image hosted on someone else's website that you don't have permission to link to. This is called "hotlinking". Again, stealing someone's bandwidth is illegal. It also slows down your page, leaving you with no control over whether the image is removed or replaced with something embarrassing. This is because the element's content and size are defined by an external resource like an image or video file , not by the contents of the element itself.
You can read more about them at Replaced elements. Note: You can find the finished example from this section running on Github see the source code too.
The next attribute we'll look at is alt. For example, our above code could be modified like so:. The easiest way to test your alt text is to purposely misspell your filename. If for example our image name was spelled dinosooooor. What exactly should you write inside your alt attribute?
It depends on why the image is there in the first place. In other words, what you lose if your image doesn't show up:. Essentially, the key is to deliver a usable experience, even when the images can't be seen. This ensures all users are not missing any of the content. Try turning off images in your browser and see how things look. You'll soon realize how helpful alt text is if the image cannot be seen. Note: For more information, see our guide to Text Alternatives.
You can use the width and height attributes to specify the width and height of your image. This presents a lot of possibilities should the need for manipulation arise. Otherwise, consider speed, performance, and manipulation when the image is a pure visual design enhancement. Want to learn how to build fast , responsive WordPress Themes with modern tools?
