A great site needs great images. Finding good ones can take up a lot of time and resources. This is a list of some of the better stock image sites out there, that have images for free or at a low cost.

When choosing the resolution that you will buy, remember that high resolution is not always better, but it does mean higher download times.

Pick the lowest resolution image that fits your needs. If you are not planning on heavily cropping or blowing up the picture often the lowest resolution will work fine. If you plan on using the image for the print medium or allowing people to print the image from your website, than a higher resolution image may be necessary.
