I duno if this helps, but when you write C/C++ programs and wants to include backslash, you have to "escape" it with an backslash. I guess the php engine is written in C or C++ and if they haven't compensated for the string parsing facilities in C/C++ then you will have to write it like this: // exec("I:\\Perl\\bin\\cjpeg.exe -quality 30 -progressive $image_name");
