Locate Online Image Libraries for WordPress Websites
Image libraries contain photos and illustrations you can use on your WordPress website. Websites use images and illustrations for headers, logos, and other design elements. If you do not use such image libraries, you will need to create those images yourself.
iStockphoto: An extensive library of stock photography, vector illustrations, video and audio clips, and Flash media. You can sign up for an account and search through its libraries of image files to find the one that suits you, or your client, best.
The files that you use from iStockphoto aren’t free — and be absolutely sure that you read the license for each image you use. iStockphoto has several licenses, and the cheapest one is its Standard license, which has some limitations.
For example, you can use an illustration from iStockphoto in one website design, but you can’t use that same illustration in a theme design that you intend to sell multiple times over (for example, in a premium theme marketplace). Be sure to read the fine print!
Dreamstime: Dreamstime is a major supplier of stock photography and digital images. Sign up for an account and search through its huge library of digital image offerings. Dreamstime offers free images, at times — so keep your eyes out for those.
Also, Dreamstime has different licenses for its image files that you need to pay close attention to. One really nice feature is its Royalty Free licensing option, which allows you to pay only once for the image, and then use it as many times as you want; however, you can’t redistribute the image in the same website theme over and over again, such as in one template, sold to the public multiple times.
VectorStock: VectorStock offers royalty-free vector-only illustrations and graphics for sale. You won’t find stock photography here because VectorStock is limited only to vector illustrations. As with other digital image resources and libraries, licenses apply to the images that you purchase and use — be sure to read about the license of the image you purchase before using it in your web design projects.
You need a vector-based editing program like Illustrator or CorelDRAW to open and use vector images.
