I'm an iStock Exclusive contributor since 2007 and I used all existed systems for uploads. I switched to qHero years ago and I believe that it is the most efficient system I ever used.

It saves me hours of keywording time because of the flexibility, intellectual content-based keywords suggestions, semi-automatic disambiguation, and effective releases management. Unique scheduling helps to plan my submissions for months ahead, and batch-oriented stats helps to track the return of investments. Cloud-based service allows uploading imagery from any of my computers then to do attribution from anywhere, which is particularly useful in travel.

qHero allows us to outsource the Keywording service and gives us the opportunity to collaborate remotely with many contractors.

One of the best features qHero offers is the simple way to copy/paste the image attributes to any submission, either active or closed.

All the releases stay in one place and you have to submit it to qHero only once, making it really simple to re-use the same release in different submissions with the same model and shoot date.
