110 Well, I can direct you to
Gatherer. In the advanced search menu, you can enter "Innistrad", "Dark Ascension", or "Avacyn Restored" under the Expansion field (be sure to OR them together instead of AND- there are no cards printed in all three sets) to get all the cards printed in the Innistrad block. You can further limit this by entering things in the different fields, such as color, type (you'll probably want Creature or Planeswalker), subtype (e.g. Human, Spirit, Zombie, Vampire, Werewolf, etc.), or any number of other things. Also, I recommend choosing the Visual Spoiler option under Output Format to make the art easier to see.
For instance, on
this page, I've entered a search for Wizards printed in the Innistrad block. Clicking Search will show you all sixteen of them. Feel free to tinker with the settings, see what you like.
Once you find something you like, they best way to get the art is to type the card's name into Google Images.
