img tag
The img tag, which, when implemented in the code, is written like this - <img>, is an HTML tag that belongs to image tags. Image HTML tags are used to insert images and their parts, including more interactive visuals, e.g. HTML maps and their clickable areas, captions for figures etc.
<img> inserts a user-specified image. This tag is supported in the current version of HTML, which is HTML5.

Attributes and values
An attribute is a piece of additional information about a tag. While tags denote the type of objects they mark or create, attributes set the parameters of these objects. These parameters can include anything from the types of possible interactions to its visual style to its actual contents.
Values indicate how a certain attribute is actually implemented, if there is a number of ways it can happen.
What attributes are actually allowed in a certain tag depends on the tag itself. Much like possible attributes depend on a tag, possible values depend on an attribute.
The <img> tag supports the following attributes (with their respective values):
| Attribute | Value | Description |
|---|---|---|
| align |
| Specifies the alignment of an image according to surrounding elements |
| alt | text | Specifies an alternate text for an image |
| border | pixels | Specifies the width of the border around an image |
| crossorigin |
| Allow images from third-party sites that allow cross-origin access to be used with canvas |
| height | pixels | Specifies the height of an image |
| hspace | pixels | Specifies the whitespace on left and right side of an image |
| ismap | ismap | Specifies an image as a server-side image-map |
| longdesc | URL | Specifies a URL to a detailed description of an image |
| src | URL | Specifies the URL of an image |
| URL | URL | Specifies the URL of the image to use in different situations |
| #mapname | #mapname | Specifies an image as a client-side image-map |
| pixels | pixels | Specifies the width of an image |
Global Attributes
Global attributes are HTML tag attributes that can be used by any tag, hence the name "global". They are in contrast to unique attributes that are tag-specific.
<img> supports global attributes.
Event Attributes
Event attributes are HTML tag attributes that allow triggering actions upon specific conditions, hence the name "event". Other types of attributes, namely global and unique attributes, can also trigger actions, but the difference is that even attributes allow calling scripts, such as JavaScript functions, while most other attributes only support a certain type of action.
<img> supports event attributes.
