ah ok
do the following.
in gallery_global.php
enable debug mode.
set: $debug_gallery = false; // change to true to see debug info
make it: $debug_gallery = true;
as your userid is 1, no need to change the $debug_userid
then go to flash upload page
at the bottom you should have the flash debug console.
upload an image, but DO NOT hit process.
check the falsh debug console at the bottom.
it should give error messages.
paste the content here.
