Marking its three-year anniversary, microstock Web site BigStockPhoto has announced two new features: Images to Go and Holiday Image & Gift Gallery. Images to Go is an efficiency-oriented feature that allows users to add search results to either shopping cart or image gallery without reviewing separate pages of image details. The holiday gallery is a seasonal offering that unites images, design ideas and publishing resources. Designers can use it to find holiday photos, while general consumers can purchase customized photo products, such as custom cards, invites, labels, wall art and calendars.
