You need to do it in dos. First you open up the dos program and find the directory and the file. Then press enter when you found the program. This will make it stay open. Or you can open dos and drag the .exe into the dos program itself and press enter.

Add to the end of the program, just before the closing bracket

getchar ();

Aha...C++...
It should be something like

...
using namespace std;
...
//your code
...
cin.get();
//end program

Just read the image file as a binary file into a buffer and go at it. This means, change some of the bytes mildly, in a somewhat organized manner. Make sure you don't ruin the header part. There is a website that gives you all the image file constructs. I think it is http://www.wotsit.org/default.asp

Can't do much harm, write the buffer back to a file (hopefully with a different filename) and look at the image with a viewer. Observe the results!

Luck -- in the picture your girlfriend now has a mustache.
No luck -- no picture, you clobbered the header!

Seriously, experiment, but first read up on the picture format a little.
