Photons Have Mass?

One thing I've always wondered, Nothing with mass can go the speed of light...right? Ok, so supposedly photons don't have mass, if they did it would take an infinite amount of energy to make them go the speed of light..right? So, then if photons do not have mass, how is it that gravity effects them? You know like, blackholes have such strong gravity that not even light can escape, stars bend light the goes around them and so forth... Someone please explain this to me... Thanks in advance.
