These are some of the coolest eyes I've ever seen

You can use Sims 2 Poster Importer, it's the easiest way (I think) to make them. That's what I use. Here's the description:
This utility will allow you to import posters to The Sims 2. You will be able to set the name, price, fun rating and room rating for every poster you create. You just need to create the bitmap and Poster Importer will do everything for you (it will automatically create a new item with every poster you import and place it in the right downloads folder).

I think it's super-easy, you should at least try it out.

Oh ok....I'm just sayin the quickest way....sorry....

Here's how I did it-easily....
When it's dark, hold down Ctrl+Shift+C and type   boolprop testingcheatsenabled true   and hit enter. Then Shift+Click on the mailbox, and click "Make me know everyone" then go to the phone, click "Call....Sim" and then find a male vampire and invite him over. When he gets there, Shift+Click on him, and click Make Selectable, then make him your active sim, and have him bite her.....it may sound like a lot but it really only takes a few minutes....oh yea don't forget to hit Ctrl+Shift+C and type   boolprop testingcheatsenabled false   then hit enter or else it might conflict with your gamelplay.
Hope I helped!
