iStockphoto has added a new collection of 'editorial use only' stock images to its site. The company says that these images are intended for use only by the media, including newspapers, magazines and bloggers  and include photos of well-known brands and people.

These images have a different licensing agreement to most stock photos, which says that they shouldn't be used commercially, including in editorially-produced marketing materials such as advertorials and client-branded supplements.

iStock says that 'Editorial use only' images will be clearly marked on its site with an orange icon, and can be filtered out. They are covered bt the same legal guarantee as commercial-use photos.
