I know someone said Yahoo maps, just confriming it is with while.

The site we use is http://www.myultimatemap.com for black and white photos. I believe it is $20 per year to use them and no limit to the maps you save. We have 40k - 50k acres in 5 states and have maps for every inch of it.

Third Eye Maps seems pretty decent... not sure if the prices are decent but great photos!
