                        $point = explode(':::', $value);
                        $map .= '<area shape="rect" coords="'.($point[0]-3).','.($point[1]-3);
                        $map .= ','.($point[0]+4).','.($point[1]+4).'" href="#" title="';

Hello,

I'm having the very same problem... I think it is that the variable $_GET['points'] is empty or sort of.

Anyone knows a way to solve this?

All best,
Will

Maybe you could temporarily turn on all PHP errors and notices and retry. Maybe something will be reported? The gzuncompress() requires the input parameter to be a string compressed with gzcompress() which is done here:
"cnt51.inc.php"

Code: Select all

echo '&points='.base64_encode(gzcompress(implode(':|:', $map_xy)));

Garbage In ~might equal~ Garbage Out ( in other words...proper Extraction requires proper Compression )

Code: Select all

string gzuncompress ( string data [, int length])

This function takes data compressed by gzcompress() and returns the original uncompressed data or FALSE on error. The function will return an error if the uncompressed data is more than 256 times the length of the compressed input data or more than the optional parameter length.


Just a thought!
