Now I haven't got any problem with GD or LIW... only the albun doesn't work..... now I'll try to disable GD.
Trust me... your host have limited in some way the getimagesize function... maybe it's a problem of memory limit.
Try to insert this at the beginning of your album_common.php
your OTF gallery is working.
but why your pictures are opening in new window?
and after refresh is showing picture location
In OTF gallery there are only small pictures, that could be the reason...
, try to upload via FTP some big images into album_mod/uploads/otf/demo/
then try to launch album_otf.php
