WML - Images
The <img> element is used to include an image in a WAP card. WAP-enabled wireless devices only supported the Wireless Bitmap (WBMP) image format.
WBMP images can only contain two colors: black and white. The file extension of WBMP is ".wbmp" and the MIME type of WBMP is "image/vnd.wap.wbmp".
The <img> element supports the following attributes:
| Attribute | Value | Description |
|---|
| align |
| Alignment of the image |
| alt | alternative text | Sets an alternate text to be displayed if the image is not displayed. |
| height |
| Height of the image in pixels or percentage. If you specify the value in pixels, the syntax is "140", instead of "140px". |
| hspace |
| Sets white space to the left and right of the image. If you specify the value in pixels, the syntax is "140", instead of "140px". |
| localsrc | cdata | Sets an alternate representation for the image. If this attribute is set, the browser will use it instead of the "src" attribute. |

How to Make ".wbmp" Images
There are free tools available on the Internet to make ".wbmp" images.
The Nokia Mobile Internet Toolkit (NMIT) comes with a WBMP image editor that you can use. You can convert existing GIF or JPG image files into WBMP file using NMIT.
Another free tool is ImageMagick, which can help you to create WBMP images.
