Hmm some good questions Adam

The thing to remember is who is going to look at the images and that will be Graphic artists and designers and web sites... So images that appeal to them will sell best... In my view it is better to submit your work to some of the better agencies who then tend to commision you to do certain topics they can sell and that way you will get a faIr recompense for your labours..

Also saves you from sending in masses of your work you have no idea what will be done with it..
