I was recently invited by Getty (through flickr) to add a selection of my photos to the Getty Stock Image Catalogue. You can find them here: www.gettyimages.com/Search/Search.aspx?assettype=image&artist=Alexander+Ipfelkofer

It’s a start! If you are in the business of licensing images, feel free to take a look, if you know someone who has needs in that regard, please forward!
