Images are very popular on our site. The biggest problem we have with images is the tendency to 'count'. We have pretty much stopped submissions to review sites because they count the quantity rather than the quality of images. The most verbal surfers seem to have a similar reaction. From a shoot with 200 images, you will likely get 30 where the model, both face and the body all look great. Add in the factor that the image needs to be substantially different than the other images in a set and you cull them out pretty quickly. We have checked the popularity of high quality unique sets vs those that have a hundred images that are just slight variations and the the sets that have fewer images get more clicks for sure. So we are back in our comfort zone of far fewer images that are each hot and high quality. Our member behavior is very different then what the convential wisdom seems to say. I believe the quality of the images must be as good or better than the quality of the video. Having high quality photography is well worth the money in my book.
