I'm never happy. If you wanted people to think they didn't HAVE to post a picture, you would've said something along the lines of "Post hot actresses if you'd like!". They way you posted it, it made it sound like if you didn't post a hot actress, you wouldn't be ridiculed. Which frequently occurs in topics such as these(see Schmarth's posts). These usually turn into spam fests and flame fests. Just look at the Paris photo. Some guys liked her, others didn't. More occurences of this can erupt into conflict, which I assume you don't want.
Monica is super sexy, btw.
