What's New in Version 1.70

New feature: The program solicits whether to overwrite the original files while exporting.
Major bugs were fixed:
1.The filename extension after saving may disaccord with that of original.
2.The capital file format .JPG was tampered into lowercase .jpg without any hint.
3.The dimensionality remains unchanged while resizing.
4.The result of resizing lacks conformity with what was set.
5.The interface will not response if a folder is being create while exporting.
