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. Royalty rate is good compared to other sites at 40%. If it was not for the unique selling point I might not even be reviewing vivozoom.
I feel i've been more than diligent uploading (attempting to upload) to vivozoom over the past couple of years. As of today there are still some basic problems with the site, the upload process, batches of images vanishing, poor interface etc. With no signs of improvements being made I'm forced to draw the conclusion that this site is dead; and in doing so I recommend you look elsewhere to sell images.
