Hi,

This is a long shot but I realized problem went over my head.
I have a java script that, downloads bunch of daily comics. Its function to generate date, and formatting.
You can find it here
I'm a graphics artist, not a programmer, scrapped it out from various snippets, and somehow managed it to work.
What I really wish is a select date function, so it can display comics for previous days.
But my knowledge stopped at 'how to reload the image once its displayed problem'

So: my questions:
How difficult it is to do? Could I expect anyone to do that out of good will, if so,
Can anyone help me out by fixing it? cause I have no idea where to start.
