The textOpacity, textColour, borderColour and borderWidth parameters supply
CSS parameters
The sTwidth parameter takes an integer value, corresponding to width in pixels. The default is 500. Depth and maximum-depth are calculated automatically. Not tested in extremely small/large scenarios - use sensible values.
The whichYear parameter specifies which year's picture to display. It may be given as a 4 digit number between 2008 and the current year (2024) incl., for example:
{{User:Begoon/POTD custom|whichYear=2010}}
If not provided, whichYear defaults to a
pseudorandom year between 2008 and the current year (2024) incl.
