-----------------------------------------------------


1) Description:

The installation of gallery write installation log file
and .inc file, where are registered login and password
of master account, the login is in plain-text the instead
the password is an encrypted md5. It the positions of
criticals files,

/g2data/Installog-*.txt
/g2data/cache/entity/0/0/*.inc

Now if you want, you can get all file and read the data
of master, and others.


2) Proof of concept:

curl "http://example/gallery2/g2data/cache/entity/0/0/[1-2].inc" -o
"#1.data"
(note: thats numbers of *.inc are random!)

reading these files:
