&c=[columns]
&x=[x size of component tiles]

1. Array of image IDs:
   An underscore [_] separated list of single-image ID's. See the function for breakdown. Maximum image's in a URL is theoretically 449 but the server will more than likely melt if this is attempted. Defaults to 8 solid colour tiles.
   Example: *a=wl010_cl021_fr032
2. Background Color [disabled]:
   Specify a background color for images. Takes 3- or 6-character hexadecimal color values. Defaults to "transparent". This code is internally converted to an RGB value and alpha is automatically toggled to full for non-transparent values.
   Examples: b=ffffff (white), b=000000 (black), b=0000ff (blue).
3. Columns:
   Specifiy the number of columns. Only used when multiple image IDs are specified. Defaults to 1.
4. Tile X-axis:
   Final x-axis/horizontal size of the tiles in pixels. All tiles are square. Final canvas size is (x-axis*columns)px x ((total images / columns) * x-axis)px. Defaults to 200.
