If you need attractive images on a tight budget, there are many good stock-photography sites that let you choose from thousands of images with prices starting at just a few buck per shot. But while these sites generally do monitor the artwork being submitted for purchase, they don’t guarantee that the images you download won’t run afoul of trademark or copyright issues.
Vivozoom offers subscription plans starting at $279 a month for up to 15 downloads a day, or pay-as-you-go plans starting at $49 for 12 Web-resolution images.
