Probably behind the curve on this one, but ah well.
Image Comics has a splendid sampling of their books up at their website. These are full scans of the first issues of quite a few of their series, including:
Age of Bronze #1 - by Eric Shanower
Dynamo 5 #1 - by Jay Faerber and Mahmud A. Asrar
Elephantmen #1 - by Richard Starkings and Moritat
Godland #1 - by Joe Casey and Tom Scioli
I Kill Giants #1 - by Joe Kelly and J.M. Ken Niimura
Invincible #1 - by Robert Kirkman and Corey Walker
Lions, Tigers, and Bears #1 - by Mike Bullock and Jack Lawrence
Noble Causes #1 - by Jay Faerber and Patrick Gleason
Proof #1 - by Alex Grecian and Riley Rossmo
Suburban Glamor #1 - by Jamie McKelvie
It's definitely a collection worth browsing, even with the amount of page-scrolling that has to be done. My favorites out of the bunch include Age of Bronze, Eric Shanower's epic endeavor to illustrate the story of the Trojan War; Elephantmen, Richard Starkings' story of genetically engineered war veterans in a sci-fi dystopia; Lions, Tigers, and Bears, in which a pride of stuffed animals comes to life to fight the things that go bump in the night; and Proof, following the adventures of Bigfoot as federal agent specializing in cryptozoological cases.
( For scans, a repost of a series that I very much wish was in that sampling. )
