Introduction
Good looking graphics are an important part of the layout of web pages. But creating graphics can also be very time consuming. Especially, if it involves creating the same type of headers, only with different text.

Therefore, Challenger features graphic tags that create images. They can be used to draw analog clocks and graphical headers as well as diagrams.

File Formats
Some of the tags take images as attributes. For example, to use as background. The images can be in GIF, JPEG, PNM or PNG format.

Color Attributes
Color attributes can be specified in one of the following ways:

`name`
  For example black or darkred.

`#RGB value`
  The color is specified as a hexadecimal-digits, `#RRGGBB`. For example, #ffdead or #00ff00.

`@HSV value`
  The color is specified with the syntax `@h,s,v` where h is the hue specified as degrees (0 to 359), s is the saturation specified as a percentage and v the value also specified as a percentage. For example, @150,70,70.

`%CMTK value`
  The color is specified with the syntax `%c,m,t,k` where all the values are percentages. For example, %10,20,30,40.
