If my photos were used, I'd get a photo credit and a link to my flickr account.
I gave them the go-ahead, figuring they'd probably opt for photos from, y'know, actual photographers with training & skill.
But, no, they did indeed use my photos. Sweet! They're part of the Golden Gate Park & SF Botanical Garden at Strybing Arboretum sections.
These are the photos in question (click on the thumbnail for the full magilla...)
Thanks, Schmap Guides!
