Thanks a lot, I changed permission and now it works!

I have installed 1.7.1. simpleviewer version into my site. It is working fine with demo images which included int simpleviewer 1.7.1. zip package, but I cannot add any of my image to gallery.

The gallery starts to load. The squares for thumbails created, but loading cannot be completed. Gallery srceen seems like
http://muda.aragos.ru/Gallery/index.html

To add new image to the gallery I used both buildgallery.php and manual mode. No effect in both cases. Access permission for all gallery files & folders set as 777

The gallery with troubles you may see at

Please help me to configure the gallery
