We use html code
In HTML, the <img> tag is used to embed images into a web page.
The src attribute
specifies the URL of the image. Here are the key points:
- src Attribute:
- The src attribute contains the URL pointing to the image you want to
display.
- It can be either an absolute
URL (linking to an external image hosted on another website) or
a relative URL (linking to an image hosted within the
same website).
- Example
<img src="URL"
style="display:none;">
