Hi.
I added a function which you can change jpeg quality with registry to mspaint.exe.

You can download English version from Here (You can find "mspainten" in article )
It use the following registry
HKEY_CURRENT_USER\Software\Microsoft\Windows\CurrentVersion\Applets\Paint\Settings
JpegQuality REG_DWORD
(Original mspaint value is fixed 75%)
If you use Win2000, you should install gdiplus.dll to your PC. :3
# Updated v.5.1.2600.5920 Changing Paste mode to Win2000 compatible!
