Photo agency Alamy are now providing vector graphics ‘as part of its strategy to provide a full service to image buyers.’
Vectors are scalable and can easily be resized without altering the quality of the image. If you print a vector logo on a small sheet of paper, and then enlarge it to billboard size it will keep the same sharp quality.
500,000 vectors are now online – view a sample of those here – Alamy is aiming to double it’s vector content by 2015
