Are there any restrictions on microstocks image using?
Yes, there are some. Each microstock has his own conditions. Usually it is prohibited to use images in cigarettes & alcohol advertisements, drug ads, political ads, erotic and porno materials, in social problem discussing publications (about illnesses and drug addiction) and in other context, where a picture on the image purchased will be displayed in disadvantageous sense. You can see detailed conditions and requirements on the photo stock’s license agreement page.
