Title: Pictures ディレクトリがない機種があるので再帰的に掘るようにした。

Some devces has no /mnt/sdcard/'Pictures'/ directory.
ex.
Maker : SAMSUNG (docomo)
Model number : SC-02B
Firmware version : 2.3.6
Baseband version : SC02BOMLC4
Kernel version : 2.6.35.7-SC02BOMLC4-CL1052793 se.infra@SEI-46 #2
Build number : GINGERBREAD.OMLC4

In this model mkdir() always returns false. It should be recursively, should it?
