Vivozoom is a new microstock agency, operating on the unique selling point of legally warranting images that are sold to clients. vivozoom claim to be be the only agency that warrants their images to protect the end user (the protection is limited to 25k)

As has become standard now the site offers both a pay-as-you go credit option which can be used at any time within 12 months and a series of subscription services for frequent downloaders. Cost of a single image based on smallest purchase of pay as you go credits for 'all sizes'. Much cheaper options are available for web resolution or downloads via a subscription. Significant savings made by purchasing 25 credits instead of 5, bringing the lowest pay as you go at a high resolution to $5.96

For contributors, the contract is fair, and cannot be changed without agreement from both parties. Commission rate is good compared to other sites at 40%. Everything works well, but it is yet-another-microstock-site, If it was not for the unique selling point I might not be uploading to vivozoom, but with it, the site at least stands out from the crowd so for me its worth giving a go. I'll report more after I have uploaded a reasonable number of images and on sales results at a later date.
