warning: deprecated conversion from string constant to char*

Right now I'm programming a game in C++/Qt, I'm getting a warning that I don't undertstand. Below is the error I'm getting

Ghost.cpp:62: warning: deprecated conversion from string constant to 'char*'

I'm getting a string of these warning messages.
at line 62 I have the below code.

char *ghostEyesDown2 = "eyesDown2.png";

The program compiles however I would like to remove this error but I have no idea what's wrong with this statement. If anybody could help it would be appreciated.

"eyesDown2.png" is a (const char*), while you are trying to copy it into a non-const char*.
You either have to make ghostEyesDown2 const, use strcpy, or use a C++ style string.

So,
const char* ghostEyesDown2 = "eyesDown2.png";

Will get rid of that warning.
