Here's a quick batch script that will copy a *_00 file over remaining 59. 

Some directions: 

1) save the script into unit_rot directory 
2) open the command line shell (start>run>"cmd") 
3) type "cd [your_unit_rot_directory]" <enter> 
4) type "ucopy [filename]" <enter> 

[filename] should be the name of your source *_00.png file without _00 suffix and without .png extension, for example; to copy ger_geb_42_00.png type "ucopy ger_geb_42" 

Hope this helps.
