You are supposed to create the MySQL table:

CREATE TABLE `$table` (
  `z` tinyint(2) unsigned NOT NULL,
  `x` int(10) unsigned NOT NULL,
  `y` int(10) unsigned NOT NULL,
  `hits` int(10) unsigned NOT NULL,
  `hits_month` int(10) unsigned NOT NULL,
  `hits_last_month` int(10) unsigned NOT NULL,
  `downloaded` timestamp NOT NULL default CURRENT_TIMESTAMP on update CURRENT_TIMESTAMP,
  `calculated` tinyint(4) NOT NULL,
  `image` blob NOT NULL,
  PRIMARY KEY  (`z`,`x`,`y`)
)

Example sizes for ortophoto map:

z16 = 870 000
-> jpg 12 GB
-> png 43 GB

z15 = 200 000
-> jpg 2.8 GB
-> png 10.0 GB

z14 = 50 000
-> jpg 0.7 GB
-> png 2.5 GB 

z13 = 13 000
-> jpg 182 MB
-> png 650 MB
