SO far, it works quite well, but when trying to keep the map from
going off the center, it seems to re-download the map images, is there
a way to have it smoother, or to disable destruction of the images so
they remain there?

I have a marker, which is nice, but at the moment, the map overlay
flashing every single time is very annoying.

Will be adding in Ajax support soon, so I'll copy the romap.htm so I
can leave something fully functional to be reviewed.

But it doesn't seem to be redownload the tiles, but is repeately
trying some tiles that dont exist, eg

perhaps you could refine getTileUrl to only return url within known
bounds, otherwise return a url to blank tile. Or maybe you could
actully make your server redirect to a blank tile rather than return a
404 - that might help with the flicker.
