Yes you are right! But whats the solution?
I want to know that when the bat file is being run successfully from the command prompt then why not from Php script? On the other hand if I will write some command like for example 'convert picture.jpg newPicture.png' in my batch file and run it from my script using exec(), it works and I get the desired result. (perhaps as 'convert' is from a Windows built-in program)
I have googled this issue and found many people discussed the same issue. People have suggested different solutions that worked for them but still I am struggling. Any good idea will highly be appreciated. Thanks!
