Stock Photos:
Wikipedia’s definition of stock photos:
Stock photography consists of existing photographs that can be licensed for specific uses. Publishers, advertising agencies, graphic artists, and others use stock photography to fulfill the needs of their creative assignments.
A customer who uses stock photography instead of hiring a photographer can save time and money, but can also sacrifice creative control. Stock images can be presented in searchable online databases, purchased online, and delivered via download or email.
A collection of stock photography may also be called a photo archive, picture library, image bank or photo bank. As modern stock photography distributors often carry stills, video, and illustrations, none of the existing terminology provides a perfect match.
So, how do stock photos come into play when it comes to your website? Stock photos can be used to essentially enhance the overall look and feel of your site. For example, a picture of two people shaking hands would be a good picture to put on the meet us section of your website.
Stock photos are not free, however. For truly good images there is usually a fee involved for use. Most people do not want to pay for these images as it adds up and therefore are looking for good websites that offer free images. Here is a list of websites that offer free or close to free images. ** Be sure to read the disclosures, terms of use and any other agreements. Most of these sites also offer images for a fee and it is sometimes hard to tell which ones are free. Additionally, many terms of use agreements state that the images cannot be used to make a profit. So for all you not for profits organizations out there, you may have just found your loophole to the stock photo issue.
