minor changes

I fixed the game page, so it will properly show a button next to each
solutions, removed the hard coding for the picture links. From what I
can tell, the new code should display an image, if there were images set
for each problem/solution in the database. I think it is trying to copy
the pictures into the pluvali root folder, there are two pictures there
anyhow that I didn't add, but they didn't copy correctly either.
