Where to find free images for your website or blog may be a challenging task if you don't know where to look. And even if you find such images, a million questions come to mind: are the images copyrighted? May I use them on a product I want to sell? Do I need to credit the photographer? In this MasterNewMedia guide I would like to help you by sharing a) some recommendations for all independent web publishers out there and b) a list of the best free and paid image libraries available on the Internet.

Let's start with some tips:
- Do not look for your images on Google or other search engines. If you are a serious publisher you may want to rely on traditional stock photo libraries like iStockPhoto or on trustable authors and photographers who have made their work available on the Internet, either for free or for a fee. But you do not want, in any case, to browse the web and steal indiscriminately images from other websites.
- Always provide full credit and a link back for any image or photo you download from the Internet. Even if you purchased it. By giving credit you respect other people's work, you prove to be an ethical publisher and you also provide visibility and exposure to the producer of the image you are using.
- Pay greater attention to the license of the image you want to use. Depending on how the photographer released her work, you may not be able to use the image commercially, to make edits to it, to display the image more than a x number of times, and so on. Check carefully what you can and cannot do with your images.
- Distinguish between "free" and "royalty-free": these are two completely different animals. A free image is free to download and use for as long as you want and wherever the author allows you to. A royalty-free image instead is an image that you pay for once and then use where and when you like without spending an extra dime (unlike traditional copyrighted images where you pay royalties every single time you display an image.)
