Well if the sidebar details any of those systems, if they exist, including that in a screenshot would be helpful yeah. Anything that gives an understanding of not just the taste in women that are there, but also the gameplay would be helpful. For instance, if you navigate by a list and just click on an item on the list, or if there are picture links acting as UI elements, that might be a good thing to screenshot as well. If there is a map system that would be good to screenshot too.
To be clear I don't expect all of these things to be there. I read your post about this mostly being a sort of demo/prototype as you get a feel for things, and that is cool. But whatever you do have from gameplay perspective, it would be best if your screenshots can display some of that and not just the actresses. Hell, if your sidebar details a stat or money system, you can have screenshots of that included with the images of the ladies. It probably wouldn't be a bad idea to include a screen with a sample of the game's writing, just to give potential players a glimpse of what they are downloading.
Best of luck with the new game.
