When purchasing stock photographs and images online, some helpful tips include avoiding overly popular images, using refined search methods and shopping around for different prices on the same image. It's also a good idea to make sure the license of any particular image suits your needs.
Stock photos are usually sold to the public at large, so certain images may be overused online. Purchasing a stock photograph that is featured on many other websites may be a bad investment since it would fail to make your website or product stand out.
When searching a stock photography website, refine your in-site search terms to quickly find the best image for your needs. To refine your search, add more keywords to your search string, use Advanced Search parameters to specify the desired size or shape, or choose certain terms to exclude from a given search.
Some images are cross-posted on different websites for different prices. Scanning the inventories of other stock photo sellers for identical listings of the same photograph can potentially save you money.
Finally, make sure the stock photo license you intend to purchase is the correct one. A royalty-free license gives the standard rights of image usage, while a rights-managed license constrains what you can do with the photograph.
