I'd use frame_number instead of clock like this:

  image_map { tga concat("D:\\sketches\\follow",str(frame_number,-4,0),".tga")

Do you have read permission for that folder? If you don't have read permission, 
you can't access the files if the I/O restrictions are active.
You may need to add a line like this to the "pvengine.ini" file from the \ini 
folder:
in the section [Permitted Input Paths]
3=D:\sketches

The number is to follow the last number in that section.
