My friend told me that I can do it using photo shop but I dont know how and also he doesn't know
Instead of retyping a set of instructions that someone else already took the time to compose, I'm just going to paste the link. You didn't say what kind of drawing you wanted your photo to resemble (pencil, ink, colored pencil, charcoal), so I took a guess and chose pencil. However, as you'll see, this site has plenty of links to tech you many other effects techniques. Happy clicking...
your great !!
