Meta Photo Management is a tool for managing metadata in images and photos. Thanks to it you can write, modify and read some of the image's information, extract and save Gps' data into the picture itself, have a preview of the photo, export your data into an *.xls file.
The tool is written in python and perl, using the Exiftool's modules for managing the metadata, Tkinter and Tk for the GUI and some other from CPAN and Python's Standard Libraries for the handling of files, spreadsheets and other things.
You can also find a couple of little tools, useful if you need to handle and rename your photos, choosing or the entire folder or just some of them in the same folder. In the new Python version these new tools are put together in a unified and simpler one.
