Ok its a simple old gallery page tha uses GD2+ Library to Generate images thumbs from a Jpg Images Directory on your host...
here is the code needs many changes but is simple to do...
Note: You need to edit all paths and url's for the script to works on your site ...
Note2: I Use this simple script on my site http://www.mazanet.gr you can visit to see for your self how it works...
take the script and modify it if you like to make it better ...
ThanX,

It would probably make more sense to make this script available for download somewhere (e.g. here on geeklog.net) instead of posting in it a story ...
