Anyone with cforms II or TDO mini forms knowledge

Hopefully someone has an idea on this?
Im using WP-2.7 and it works fine. I have uploaded plugins cforms II and tried it and also TDO mini forms and tried it, and they work great, but I cant seem to find a way to do this.

What Im trying to do is this:
On the main front page of my site I need a form that allows the user to post directly (thats not a problem both of these plugins do that)

The problem is I need the form to have a way for the user to choose from a list of names (either via a dropdown box or a list) Then once they have chosen their selection and hit submit, it then associates a specific image to the name that they selected in the form and is now posted (on my main front page) along with their title, comment etc.. from the form.

So im hoping that someone in the great WP community might have an idea who might have used either of these two forms plugins, or maybe someones got an easier way of doing it. I hope so, Thanks
