Cushystock is no longer supported - this post is for reference only
Cushystock is a microstock keywording and upload assistant that streamlines the work of submitting images to multiple microstock agencies. Like prostockmaster it supports multiple agencies (10 at present), there is a free trial but the full version of the software costs US$ 49.95.
Unlike most of the other 'multi-upload microstock' assistants cushystock also supports raw formats. Due to the fact that I'm currently happy with my current upload system, I have not performed a full review of cushy, but the users of microstockgroup have voiced their opinions and with services like this moving into the 'cloud' I feel the days are numbered for downloaded tools like this unless you use them for a significant part of your keywording workflow.
