Hi Yefei,
I do this in my code:
osgDB::ReaderWriter::Options* opt = new osgDB::ReaderWriter::Options;
opt->setObjectCacheHint( osgDB::ReaderWriter::Options::CACHE_IMAGES );
osgDB::Registry::instance()->setOptions( opt );
which seems to solve the problem you describe. I am not sure why your method
would not work.
