Thanks, I tried it, but error message pops up,
saying "Encountered an Improper Argument".
Weird thing is, though I changed just 12700 to 12600,(just one letter is changed)
file size is original : 2947kb, recompressed one:2956kb.
What zip program do you use?
I tried Windows7 default(right click and you know..).
Edit:Finally it works. I made mistake in directory when recompressing.
