Getting pictures can be tricky in winter (due to heavy gloves) but in summer I just pull my very old canon from the back pocket and snap picture either forward or over my helmet back (those often are quite crooked ). I always make sure to put the camera back with the lens facing out (not towards my body). I actually trained to take the camera out of the pocket and put it back so it would be always exactly in position as I want to.

Here are some of my pics I took while riding:


( I like this one because one can see the motion on the side of the pics but the center is somewhat sharp )




And of course, one can take pictures of herself (so vain!)


There are many helmet cams - mostly advertise on motorcycle forums - which do take pictures (remote control) or videos. They are sold as a whole setups and the last time I looked, it was around $300 for helmet cam, wires, the actual camcorder and everything else.
